摘要:

为了提高永磁同步电机转速控制的阶跃响应和抗负载突变能力,本文在比例积分( proportional-integral,PI) 控制基础上融合积分比例( integral-proportional, IP) 调节器和抗饱和控制,形成带抗饱和功能的PI-IP双等级自由度控制器。基于永磁同步电机机械运动方程分析了PI和IP两种控制方法的特性。通过伯德图分析研究 PI-IP 双自由度控制的特性,从理论上证明改进方案的可行性。通过仿真验证了所提方法的有效性。仿真结果表明,改进方法与传统 PI 控制比较,系统在转速突变时超调量降低显著;负载突加突减时,稳定性提高。

Abstract:

To improve the step response and the capability to resist abrupt load variations of the permanent magnet synchronous motor (PMSM) speed control, an integral-proportional (IP) regulator with anti-windup controller was integrated into a traditional proportional-integral (PI) speed controller, forming a PI-IP dual-degree-of-freedom controller with anti-windup functionality. The characteristics of PI and IP control methods were analyzed based on the mechanical motion equation of the PMSM. The properties of the PI-IP dual-degree-of-freedom control strategy were investigated through Bode diagram analysis,theoretically demonstrating the feasibility of the improved scheme. The performance of the proposed method is evaluated through simulations. The results indicate that compared with traditional PI control,the improved method significantly reduces overshoot during sudden speed changes and enhances stability under abrupt load variations.

Key words: permanent magnet synchronous motor, speed control, proportional-integral control, proportional-integralintegral-proportional double-degree-freedom controller
