基于MCP标准函数的永磁同步电机电流环PI控制

Multi-Capacity Process Standard Transfer Function Based Current Control of PMSM

永磁同步电机(PMSM)伺服控制系统要求有快速响应的电流环,以获得良好的控制性能。针对PMSM电流环的控制,提出一种基于多容过程标准传递函数的PI控制方法,该方法参数计算简单,电流跟踪效果好,抗干扰性强。仿真结果表明,与工程设计PI法相比,该方法对PMSM电流环控制有很大的优越性。

In order to get high dynamic performance of the whole system, permanent magnet synchronous motor servo（PMSM） applications require fast response current inner loop. For PMSM excitation current loop, a kind of multiple capacity process proportional integral （MCP-PI） control method was proposed. The method of parameter calculation was simple, good current tracking results, strong anti-interference. The simulation results showed that this method has great advantages over the control of the excitation current loop of PMSM, compared with the engineering design PI method.
