Modeling and Simulation of IM-VC System Based on Modelica
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.
