Energy Recovery Control Strategy of Electromagnetic Coupling Flywheel Energy Storage Technology for Vehicles
In order to reduce the energy loss caused by stepping on the brake pedal when the car is going downhill,the paper uses the automotive electromagnetically coupled flywheel energy storage technology,builds a car energy conservation model in Matlab/Simulink,regulates the output speed of the electromagnetically coupled governor through the LADRC algorithm and the double closed-loop model carrying fuzzy PID,realizes the speed control of the energy storage flywheel,and the kinetic energy of the car is recovered from the energy storage flywheel to realize the stable driving of the car speed.The simulation results show that,when the initial speed of the car is 40 km/h,the LADRC can control the car speed stably in 0.62 s and can store the incremental kinetic energy of the car in the flywheel,which has good control effect,and reduce the wind resistance loss that the car overcomes when going downhill,re-duce the energy loss of the car and improve the energy utilization efficiency.
