A hybrid electric vehicle is powered by an internal combustion engine and one or more electric motors that use energy stored in batteries. It is not possible to connect a hybrid electric vehicle to charge the battery. Instead, the battery is recharged by regenerative braking and the internal combustion engine. Additional power is provided by electric motors, which may allow for smaller motors. The battery can also power auxiliary loads and reduce engine idling when stopped. Combined, these features improve fuel economy without sacrificing performance. Curriculum usually includes: Course description Course goals and objectives Course topic Course review times and/or schedule Required materials/textbooks rating scale Time-bound mandatory activities and assessments course policy Key components of hybrid electric vehicles Battery (auxiliary battery): In EV vehicles, a low-voltage auxiliary battery provides power to start the vehicle before the traction battery is turned on. It also powers car accessories. DC/DC converter: This device converts high voltage DC power from the traction battery pack to the low voltage DC power required to operate vehicle accessories and charge the auxiliary battery. Generator: It generates electricity from the spinning wheels during braking and returns this energy to the traction battery. Some vehicles use a motor-generator that performs both propulsion and regeneration functions. Electric traction motor: This motor uses power from the traction battery to drive the wheels of the vehicle. Some vehicles use a motor-generator that performs both propulsion and regeneration functions. Exhaust system: The exhaust system directs exhaust gases from the engine to the outside through tailpipes. Three-way catalytic converters are designed to reduce engine emissions in the exhaust system. Fuel filler neck: The fuel pump nozzle is connected to the vehicle's tank and fills the tank with fuel. Fuel tank (gasoline): This tank stores gasoline in the vehicle until the engine needs it. Internal Combustion Engine (Spark Ignition): In this configuration, fuel is injected into either the intake manifold or the combustion chamber where it mixes with air and the mixture is ignited by a spark from the spark plug. Power electronics controller: This unit manages the flow of current supplied by the traction battery and controls the speed and torque of the electric traction motor. Heating system "cooling": The system maintains proper operating temperature ranges for engines, electric motors, power electronics and other components. Traction battery pack: Stores electricity for use by electric traction motors. contagion; infection: The transmission transfers mechanical power from the engine and/or electric traction motors to drive the wheels.

Overview The automatic control for the molten steel level of the mold is one of the key technologies of continuous casting production. It is very important to reduce the labor intensity of workers, improve production efficiency, improve the quality and output of casting billet, reduce overflow and breakout of steel and improve the management level of steelmaking and continuous casting. The molten steel is poured into the mold. In order to prevent overflow, the molten steel level must be kept stable. Otherwise, during the casting process, if the level will fluctuate too much, and slag will be involved, forming surface slag inclusion on the surface of the casting billet, affecting the quality of the billet. The test points out that the relationship between the level fluctuation and the depth of casting billet surface slag inclusion is as follows: The experience has shown that surface slag inclusions can be eliminated when the level fluctuation is within ±10mm. At the same time, if the level fluctuation is more than 10mm, the rate of longitudinal cracks on the casting billet surface is 30%. It means that the level fluctuation directly affects the surface quality of the casting billet. The principle of the system The eddy current type molten steel level gauge is the key to the system. The system operates reliably and has excellent performance: high temperature resistance, strong anti-interference ability, fast dynamic response (lag time 0.10s), high detection accuracy (±05mm), and large measurement range (0-150mm). The selected electromagnetic field frequency ensures that the level detection probe only detects the level change of the mold and does not detect the mold flux or steel slag layer. The system has the advantages of simple operation and no radiation protection problems. The system is insensitive to argon blowing, and its sensors can be mounted on the tundish car or on the platform. The sensor is cooled by compressed air during use. The principle is shown in the figure A high-frequency exciting winding is installed above the molten steel surface of the mold. The high-frequency magnetic field generated by the high-frequency exciting winding induces eddy currents on the molten steel surface to form a magnetic field. The magnetic field generated by the induced eddy current is in the opposite direction to the magnetic field generated by the high-frequency exciting winding, which changes the impedance of the high-frequency exciting winding. Under the condition that the winding material and structure, steel grade, temperature remain unchanged, the coil impedance change only has a single-value function relationship with the height of the molten steel level. As long as the impedance change of the high-frequency winding is detected, the change of the molten steel level in the mold can be converted. The components of the system Continuous casting mold level automatic control system is composed of eddy current tyoe molten steel level gauge, controller and digital actuator for adjusting the opening of tundish stopper. The detection end of the mold level automatic control system is ① eddy current displacement sensor, which uses the eddy current mutual inductance effect between the energized coil and the metal conductor to detect the distance. The effective signal of the eddy current sensor is amplified and linearized by the circuit of ② mold level gauge, which converts the 0-150mm change in the molten steel level of the mold into a standard signal of 4-20mA.DC, and then transmits it to the ③ control computer to complete data processing and system control functions. We can also control the actuator manually and automatically through the ④on-site operation display control panel, and the opening of the stopper is controlled by the ⑤ actuator to realize the automatic control of the molten steel level. 1 Eddy current sensor; 2 mold level gauge; 3 control computer; 4 On-site operation display control panel; 5 digital actuator; The control principle of the system The system can be set to four control modes: automatic, semi-automatic, manual and motor clutch. The automatic mode is the closed-loop control system of the molten steel level, and control the opening of the stopper by the digital actuator; the semi-automatic mode uses opening degree setter and digital actuator to set the opening of the stopper manually; the manual mode is to open and close the button directly to control the opening of the stopper; the motor clutch mode is quickly changed from any of the above control methods to manual stopper operation. The functions of the system also include: display and record of molten steel level, nozzle opening and casting speed; setting of molten steel level and nozzle opening; alarm of molten steel level at limit value etc. In addition to taking the detection of molten steel level as the main feedback signal of the control system, the control system also considers various interference factors that have an impact on the level control. These interference factors include: 1. The influence of the change of the flow characteristics on the control system after the melt loss of the stopper 2. The influence of the weight change of molten steel in the tundish on the control system 3. The influence of the change of the casting speed of the continuous casting machine on the control system 4. The influence of the mold width change (the mold width is adjustable) on the control system 5. The influence of the vibration frequency and amplitude of the mold on the molten steel level gauge The function and software implementation In order to overcome these disturbances, the mold level control strategy adopts PID control. And on the basis of PID control, self-adaptive correction and feedforward control are introduced to form an advanced control system. The level control is the main loop, and there is a proportional gain of the main loop controller. According to the self-adaptive correction of the mold width change and feedforward compensation of casting speed, so as to further reduce and eliminate liquid level fluctuations caused by mold width adjustment and casting speed changes. In order to reduce the frequent action of the stopper, the system adopts the intergarting time change of the controller, and automatically selects a longer intergarting time when the molten steel level fluctuates lightly. And the system will choose a shorter intergrating time when molten steel level fluctuates greatly. Thereby, the fluctuation of the controlled object caused by the frequent action of the stopper rod is suppressed. In the signal processing of molten steel level gauge, an appropriate filtering link is added and the vibration frequency synchronous filter is used for filtering processing, which can overcome the interference of mold vibration frequency and amplitude variation.
