摘要
为了提高各种复杂环境条件下永磁同步电机(PMSM)控制器的动态控制性能与抗干扰能力,分析了永磁同步电机的速度-电流双闭环控制调速系统的结构,提出了一种参数自校正的模糊PI控制策略。上述模糊PI控制器运行时首先将永磁同步电机转速的误差及误差变化率进行模糊化,然后依据模糊规则进行模糊推理,自动整定出速度环PI的两个参数的校正因子,在运行过程中,模糊参数采用分段法进行在线校正。通过MATLAB仿真结果表明,当永磁同步电机的转速发生变化或负载发生扰动时,参数自校正模糊PI控制器动态性能与鲁棒性更有优势。上述控制器用于永磁同步电机的控制是可行、有效的。
To improve the dynamic response speed and disturbance rejection ability of Permanent magnet synchronous motor (PMSM) controller, by analyzing the double closed-loop control system structure of velocity and current loop for PMSM, a self-turning control strategy based on the fuzzy PI control principle was proposed. The fuzzy PI controller firstly fuzzed up the error and change rate of error of rotate speed for PMSM. Then it carried out the fuzzy reasoning based on the fuzzy rules, and adjusted automatically the correcting factors for PI of velocity loop, which can not only reduce the adjust time of the velocity loop, but also reject the disturbance of the current loop. The simulation results show that the proposed method can improve the dynamic performance and robustness of the system. The proposed method is feasible and effective for the PMSM control.
