摘　　要：从电励磁双凸极电机(DSEM)的基本原理出发,设计了基于滑模变结构控制(SMC)的双闭环驱动系统。该系统的转速外环采用变指数趋近律的SMC,电流内环釆用滞环控制。基于有限元分析法建立了DSEM驱动系统的场-路联合仿真系统,与外环采用比例积分(PI)控制、内环采用滞环控制的双闭环驱动系统进行仿真及实验对比。结果表明DSEM驱动系统采用SMC可提高电机的转速响应速度,具有很好的鲁棒性。A double closed-control system for driving doubly salient electro-magnet machine ( DSEM ) is designed, in wh? ich sliding mode variable structure control (SMC) with variable exponential reaching law is adopted for the outer speed loop and hysteresis control is adopted for the inner current loop. Based on the finite element analysis method, a fieldcircuit simulation system is established. Simulations and experiments are carried out, and comparisons are made with the double closed-loop driving system with proportional integral (PI) control in the outer loop and hysteresis control in the inner loop.The results show that SMC has good robustness and it can improve the response speed of DSEM.
