基于MCP标准函数的永磁同步电机电流环PI控制

摘要

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.%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.
