摘要
为有效解决传统模糊控制器用于无刷直流电机直接转矩控制存在的超调高、响应慢、脉动过大等缺陷,将模糊逻辑与PI控制相结合形成模糊自整定PI控制方案,使用遗传算法改善和优化模糊PI控制器的控制规则及其参数因子K_e,K_(ec),K_u P,K_(uI)。仿真结果表明,基于模糊PI控制的直接转矩控制对于高非线性的BLDCM取得较为满意控制效果,提高系统的动态响应和鲁棒性。
In order to effectively solve the defects of high overshoot, slow response and big ripple with traditional fuzzy controller applied to BLDCM＇s direct torque control, fuzzy logic was combined with the PI control to form the scheme of fuzzy self-tuning PI control. The genetic algorithm was used to improve and optimize the fuzzy control rules and parameters of PI controller factor Ke ,Kec ,Kup ,KuI. The simulation results show that the direct torque control based on fuzzy PI control of BLDCM for high nonlinear achieves relatively satisfactory control effect, and improves the system dynamic response and robustness.
