发动机怠速脉动开关磁阻电机主动阻尼控制

针对发动机怠速脉动控制问题,应用基于开关磁阻电机的车用ISAD系统作为辅助扭矩源实现发动机怠速脉动主动阻尼控制.基于抗周期性干扰原理构造控制系统,以内燃机输出的周期性扭矩为扰动,用开关磁阻电机来产生耦合扭矩来减小发动机扭矩脉动,并通过模糊自适应PID控制器控制ISAD系统的输出扭矩.最后用MATLAB建立起仿真数学模型,得到主动阻尼控制系统的仿真结果来验证控制方式的有效性.

Switched Reluctance Motor Active Damping Control for Engine Idle Speed Oscillation

In allusion to the engine idle speed oscillation,ISAD based on switched reluctance machine is used as a supplemental torque source to realize active damping of the engine idle speed oscillation.The system is based on the classical idea of the periodic disturbance rejection.The torque generated by the combustion engine is a disturbance,and the switched reluctance machine generates a coupling torque to compensate the engine torque ripple.The torque of the ISAD is controlled by fuzzy adaptive PID controller.In...
