Incremental motion control of synchronous reluctance motor via multisegment sliding mode control method

This paper solves a particular incremental motion control problem, which is specified by the trapezoidal velocity profile, using multisegment sliding mode control. Each segment of the multisegment switching surfaces is designed to match the corresponding part of the trapezoidal velocity profile, so that the motor dynamics on the specified-segment switching surface have the desired velocity or acceleration corresponding to the trapezoidal profile. The multisegment sliding mode control is applied to a synchronous reluctance motor system to demonstrate its effectiveness. A PC-based prototype system is built to verify the validity of the proposed scheme.
