In this paper, a passivity-based control (PBC) algorithm with disturbance estimation is proposed to obtain precise position control of a Linear Switched Reluctance Motor (LSRM) driving system. Following the modeling analysis of the driving system, a full-order controlled model is first developed. On the basis of the state error equation, the proposed robust PBC algorithm is derived from the view of energy dissipation and the global stability of the whole servo system is insured by the proposed algorithm in turn. Through the disturbance estimation, it can also reject the effect from external disturbances and make the servo system achieve precise position tracking. Simulations and experimental implementations carried out on the proposed LSRM driving system demonstrate that the proposed control algorithm is effective for the LSRM position tracking system.
