Abstract: There is still lack of effective modelling, simulation and optimisation methods for complex electromechanical system. In this paper, the dynamics model of the PMSM-precision reducer system is established using Lagrange-Maxwell equation. The simulation model and optimisation model of this system are set up with Modelica language. The simulation and optimisation of the system are realised in Dymola and JModelica.org platforms respectively. Simulation results show that the dynamics model of the system is correct. Optimisation results show that the system can quickly respond to the given speed and loads. The proposed modelling, simulation and optimisation method based on Modelica may be commonly applied to other complex electromechanical systems.
