摘要
研究一种基于干扰观测器滑模控制(DOB-SMC)方法。为实现永磁同步电动机良好的静态和动态跟踪性能,设计了一种基于指数趋近律的滑模控制器,并证明了滑模控制器的渐近稳定性。引入基于DOB的滑模控制器以补偿负载干扰,从而保证系统的鲁棒性。仿真与实验证明,该方法提高了永磁同步电动机控制系统速度跟踪精度,并且对负载干扰具有较好的抑制效果。
A disturbance observer-based sliding mode controller design method was proposed. In order to realize the static and dynamic tracking performance of the motor system, an exponential approach law-based sliding mode controller was designed. On the base of this, to compensate the load disturbance, the disturbance observer-based feedback controller was introduced, the robustness of the system was guaranteed. Simulation and expriment results show that the proposed method improves the speed tracking accuracy of PMSM control system and can restrain the load disturbance effectively.
