A new motion controller ensuring finite-time stability for permanent-magnet linear motor (PMLM) system is investigated in this paper via second-order sliding mode (SOSM) control technique. Firstly, by choosing position error as sliding mode variable, the position dynamic error system is derived for PMLM system. Then, by appropriate assumption that the lumped disturbance is bounded by a positive function, a new SOSM controller is constructed by using the adding power integrator technique. Strict mathematical analysis is provided to show that the proposed SOSM controller could steer the current position of PMLM to the desired position in finite time. Finally, the claimed performance of the proposed control strategy is illustrated by simulation results.
