PMLSM Position Control Based on Energy Shaping Method

Abstract

Aiming at the position control problem of permanent magnet synchronous linear motor (PMLSM), the PMLSM Hamiltonian function was built based on Hamiltonian feedback dissipative control strategy in the perspective of energy shaping. First, a speed controller was proposed, then a position control outer loop was added to control closed loop, the PMLSM position control was realized with feedback dissipative method. The simulation results shown that the proposed method can ensure system has fast response, small tracking error and good robust performance, and also simplify system parameter setting.
