针对具有非线性、强耦合和参数摄动特性的六相永磁同步电机转速控制问题,提出了一种新型指数趋近律并用于六相电机滑模调速系统,该趋近律将趋近速度与系统状态误差和滑模切换函数相关联,在增大趋近速度的基础上有效抑制了常规滑模控制固有的抖振现象.基于自适应模糊逼近思想,将新型指数趋近律中的切换项连续化,消除了滑模控制的抖振缺陷.仿真结果表明,基于新型指数趋近律的滑模控制策略响应速度快、控制精度高,而且对参数摄动和负载变化具有较好的鲁棒性,可以改善六相电机调速系统的动态品质.“,”This paper proposes a novel exponential reaching law of sliding mode for the six-phase permanent magnet synchronous motor speed regulation system with the characteristics of nonlinearity, strong coupling and parameters perturbation. The novel reaching law, associated with the changes of the system state and sliding mode, can overcome the disadvantage of the traditional reaching law, suppress the chattering and improve the reaching speed. Continuous function is established in the reaching law based on the adaptive fuzzy theory to eliminate the chattering. The simulation results show that the novel exponential reaching law sliding mode control can improve dynamic response performances and robustness characteristics of the six-phase permanent magnet synchronous motor speed servo system.
