摘　　要：对数控磨床永磁同步电动机直接驱动系统的速度进行模糊控制研究。模糊控制器可以根据速度误差以及误差的变化,按照模糊控制规则给出控制量,特别适合于数控磨床永磁同步电动机直接驱动的非线性控制系统。模糊控制表的建立是离线进行的,没有影响模糊控制器实时运行的速度。一旦模糊控制表建立起来,模糊控制的算法就是简单的查表法,能够满足速度实时控制的要求。采用模糊控制能显著提高速度控制的鲁棒性,满足数控磨床直接驱动系统对给定速度的准确跟踪和扰动的抑制,仿真结果验证了该方法的有效性。This paper presents study on fuzzy control of permanent magnet synchronous motor direct drive system for NC Grinder. According to fuzzy rules,the fuzzy controller can regulate control output by speed error and error change. Fuzzy control strategy specially fit to permanent magnet synchronous motor direct drive nonlinear system. The output of controller is achieved by a fuzzy control table. And high-speed response for fuzzy control system is guaranteed. The system robustness is strikingly improved. The fuzzy controllers can guarantee a good disturbance restraint as well as the tracks of input signal. Feasibility of the design method is verified by virtue of computer simulation.
