Research on Current Hysteresis Control Strategy of Linear Motor Suspension

本文设计出一种电流滞环控制策略,通过跟踪直线电机式悬架控制系统输出的最优阻尼力转变,得到参考电流,经过空间矢量调制后输出PWM波,输送到电流逆变器中转换为三相电流,进而控制直线电机的作用。经过仿真可以得出电流滞环控制策略控制效果良好,可以输出理想的阻尼力,为电动汽车主动悬架的研究提供基础。

In this paper,a current hysteresis control strategy is designed.By tracking the reference current obtained by the optimal damping force output of the linear motor suspension control system,the PWM wave is output after space vector modulation,and is sent to the current inverter to be converted into three.The phase current,in turn,controls the action of the linear motor.After simulation,it can be concluded that the current hysteresis control strategy has good control effect and can output the ideal damping force,which provides a basis for the research of electric vehicle active suspension.
