摘　　要：为抑制开关磁阻电机非线性结构所导致的转矩脉动,提出磁链的边界层混合滑模控制器,加入边界层内积分补偿,实现线性控制和非线性滑模控制相结合,使磁链能够平滑收敛于滑移面的平衡状态,在获得鲁棒性的同时具有平滑跟踪特性。接着,进一步论证了该混合控制器实现的稳定可达性。仿真测试分别比较了该控制器与PID、传统滑模控制的磁链跟踪性能、扰动抑制和转矩控制性能,表明该磁链控制器能获得较低脉动转矩,在不失去鲁棒性的同时有较高的抗抖振能力。最后,通过实验验证了其可行性。In order to reduce torque ripple caused by nonlinear construction a hybrid sliding mode control with boundary layer （HSMC） of flux-linkage proposed. of switched reluctance motor, using integral compensation is It was a combination of linear and nonlinear mode to cause flux-linkage to smoothly converge to a balance state of sliding surface, and further, its convergence was proved. Simulation was to compare HSMC with PID and a classic sliding mode control about tracking performance of flux-linkage, anti-dis- turbance performance and torque control. The simulation results indicate the proposed I-ISMC can achieve lower ripple torque and less chattering control without loss of robustness than the other two methods. Fi- nally, experiment results prove the feasibility of HSMC.
