摘　　要：在间接空间矢量调制的矩阵变换器和矢量控制原理的基础上,搭建了异步电机调速系统。为了进一步提高该系统的动态性能和抗干扰能力,在调速系统的矢量控制部分引入模糊自适应PI控制器,代替传统的PI控制器,对控制器参数进行实时校正。仿真结果表明,采用模糊PI控制器的矩阵变换器驱动的调速系统能够使能量回馈到电网,达到了节能目的,同时具有良好的动静态性能和抗干扰能力,相对采用传统的PI控制器的调速系统有较大的改善。A drive system based on matrix converter with the indirect space vector modulation and the asynchronous motor vector control was built. To improve the dynamic performance and the anti-jamming ability, fuzzy adaptive PI controllers were applied to the vector control loop to replace traditional PI controllers for the purposes of the real-time adjustment of the controller parameters. Simulation results show that matrix convert- er fed asynchronous motor drive system which applied fuzzy adaptive PI controllers has a capacity of energy regeneration and saving. In addition, the drive system has superior dynamic performance and steady-state per- formance,which is better than the drive system with traditional PI controllers.
