【Abstract】 A nonlinear adaptive control scheme for stepping motors is presented, and a nonlinear adaptive position controller is designed. Simulation shows that the control scheme is adaptive to parametric variations and external disturbances , and the stepping motor with the proposed controller not only has a high controlling accuracy, but also possesses the characteristic of fast response with no overshoot.更多还原
