Fuzzy controlling of servo system of synchronous electrical machinery tempo of permanent magnetism

为了消除永磁同步电动机系统参数、负载扰动等不确定性因数的影响,结合遗传算法和模糊控制,利用遗传算法对模糊控制器的参数进行优化设计,将单位阶跃函数下的ITAE积分性能指标作为评价函数,通过对隶属度函数和量化因子的优化设计,提高了速度系统的动态响应能力。仿真和实验结果证明:该方法能够提高速度检测装置的分辨率,使系统具有更强的鲁棒性。

Targeted at dispelling the influence due to uncertain factors such as the systematic parameter and load perturbation of permanent magnetism synchronous motor, the paper introduces the use of the hereditary algorithm to optimizing the design of the parameter of the fuzzy controller , combined with the hereditary algorithm and fuzzy control, the use of jump function as appraising of performance index of ITAE total mark under the function on the unit steps, and the optimization design of the quantizing factor and the jurisdiction of one degree of functions, which contributes to the improvement in the dynamic response ability to the pace system. The simulation and experimental result prove that the method can raise pace resolution ratio to measure device, which makes the system have a stronger robustness.
