摘　　要：永磁同步电机(PMSM)在交流伺服系统中应用十分广泛,其数学模型具有非线性、多变量、强耦合的特点。为提高建模与分析效率,并兼顾PMSM模型在复杂多领域系统中的通用性等问题,提出一种基于Modelica的交流伺服控制系统的建模方法。采用模块化建模与Modelica语言实现了PMSM的非因果建模,在MWORKS平台建立了伺服系统的仿真模型,并在位置控制、速度控制方面测试了3类典型工况。实验表明,所提方法跟随误差小、动态响应快,验证了建模方法和系统模型构建的正确性和合理性,为伺服控制系统和多领域建模与仿真技术的发展提供了新思路。Permanent magnet synchronous motor(PMSM)is widely used in AC servo systems,and its mathematical model has the character-istics of nonlinearity,multivariability,and strong coupling.In order to improve the efficiency of modeling and analysis,while also considering the generality of PMSM models in complex multi-domain systems,a modeling method for AC servo-control systems based on Modelica is pro-posed,the non-causal modeling of PMSM is realized by using the way of modular modeling and Modelica language,and a simulation model of the servo system is established on the MWORKS platform,three typical operating conditions have been tested in terms of position control and speed control,with small tracking error and fast dynamic response.The correctness and rationality of the modeling method and system model construction are verified,which provides several new ideas for the future development of the servo-control system and multi-domain unified modeling and simulation technology.
