摘要

Based on the simulation, the dynamic characteristics of three kinds of starting laws are analyzed. It is found that the system adopts the law of slope curve, the impact of motor speed and electromagnetic torque is too large, and the stability of the system is poor. The system adopts the simple harmonic motion law, the system has a great improvement in the stability, but the response speed is slow, and the stiffness is poor. The system adopts the law of equal acceleration and equal acceleration, with the best stability, rapidity and stiffness.
