摘　　要：针对永磁同步电机驱动控制系统在运行过程中易受非线性和不确定性因素的影响导致控制性能下降的问题,提出引入智能积分器的模糊逻辑控制方法,并应用于永磁同步电机矢量控制系统中。该方法通过在常规模糊控制器的基础上引入积分环节并对引入时机进行智能判决,使系统在保留了常规模糊控制良好的动态性能的同时改善了稳态精确度。对控制系统进行了建模和仿真。仿真结果表明:该方法响应速度快,稳态精确度高,对超调和振荡抑制能力较强,比传统的PI控制器、常规的模糊控制器以及全时引入积分作用的常规模糊积分控制器具有更好的动、静态综合性能。A fuzzy logic control with intelligent integrator was developed and applied to vector control systems of permanent magnet synchronous motor（PMSM） to improve their performance by eliminating the effects of the nonlinearities and the indeterminateness of the mathematical models.Through introducing integral capacity to the conventional fuzzy logic control system and the intelligent timing control of the introduction,the method preserves the good dynamic performance of conventional fuzzy logic control and improves its steady-state accuracy.Modeling and simulation were used in the control system.The simulation results showed that the method achieved the characteristics of fast response speed,high steady-state accuracy and good performance of restraining overshooting and oscillation and had a higher dynamic and static performance than traditional PI controller,conventional fuzzy logic controller and fuzzy integral controller with all-time integration.
