车用电磁耦合式飞轮储能技术能量回收控制策略

Energy Recovery Control Strategy of Electromagnetic Coupling Flywheel Energy Storage Technology for Vehicles

为了减少汽车下坡时由于踩踏制动踏板造成的能量损失,该文利用车用电磁耦合式飞轮储能技术,在Matlab/Simulink中搭建汽车能量守恒模型,通过LADRC算法与携带模糊PID的双闭环模型对电磁耦合调速器的输出转速进行调节,实现对储能飞轮的转速控制,将汽车增加的动能回收于储能飞轮中,实现对车速的稳定行驶。仿真结果表明,汽车初速度为40 km/h时,LADRC能在0.62 s时将车速稳定控制,且能够将汽车动能增量储存于飞轮中,具有良好控制效果,并减少汽车在下坡时克服的风阻损耗,减少汽车的能量损失,提高能量的利用效率。

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,reduce the energy loss of the car and improve the energy utilization efficiency.
