摘　　要：目前,大多数的控制系统都是非线性的,传统的PI控制虽然结构简单,不受控制对象的影响,但在一定程度上受到了局限性。而模糊控制适用于非线性系统,可根据模糊量来对系统进行精确控制。结合这两种方法的优点,提出了模糊PI自适应控制,并将其应用在永磁同步电机调速控制系统中,根据不同的情况自动调节控制器参数。经MATLAB建模仿真,验证了模糊PI自适应控制能提高系统的动态稳定性与鲁棒性。At present,most of the control systems are nonlinear. Although the traditional PI control structure is simple,without being affected by the influence of control object,it is limited to some extent. Fuzzy control is,however,suitable in nonlinear system,which can be precisely controlled according to fuzzy quantity. The advantages of combining these two methods,this paper proposed the fuzzy PI adaptive control which was applied in the permanent magnet synchronous motor speed control system to automatically adjust controller parameters under different conditions. Through MATLAB modeling simulation,the fuzzy PI adaptive control is verified to succeed in improving dynamic stability and robustness of the system.
