摘要：In order to solve the problem that the stepping motor in the manipulator is frequently stopped and the conventional index algorithm can not make full use of the output torque under the high speed heavy load, the two-stage exponential acceleration algorithm for stepper motor is proposed. Based on the critical load curve, the two-stage exponential type and the conventional exponential acceleration scheme are analyzed and compared, which proves that the former has better fastness. The critical load curve fitting is carried out by Matlab software, and the best point are selected by w-t equation. The two-stage exponential acceleration iterative algorithm is designed to reduce the dispersion of the speed-increasing process and improve the smoothness of the stepping motor acceleration process. Finally, the experimental results show that the motor speed curve under the two-stage exponential control is in accordance with the theoretical curve, and the feasibility of the method is proved.
