Modelling, Simulation and Nonlinear Control of Permanent Magnet Linear Synchronous Motor

Dr.K.Alicemary, Mrs. B. Arundhati, Ms.Padma.Maridi

This paper describes a nonlinear model of the Permanent Magnet Linear Synchronous Motor and an analogy between the rotary motor and the linear motor. Constructional details of various sub-models for the permanent magnet linear synchronous motor are given and their implementation in SIMULINK is outlined. A novel control of PMSM is designed by which the system nonlinearity is cancelled. In addition, a linear state feedback control law based on pole placement technique to achieve zero steady state error with respect to reference current specification is employed to improve the dynamic response. The extensive simulation is performed through MATLAB SIMULINK
