As it known, one of the most important disadvantages of the open-loop stepping motor-based positioning systems is the high sensitivity regarding the strongly load torque variations. The paper explores the feasibility for implementing a variable-structure position controller-based strategy for the hybrid stepping motors, in order to achieve insensivity and robustness for this actuator. This strategy can improve the dynamic response of the motor, and the insensivity regarding the motor parameters variation too. The block diagram of the proposed control structure and the variable-structure controller design methodology is discussed widely in the paper. Detailed numerical simulation results are indicated in order to prove the feasibility of the proposed control strategy.
