Abstract

The performance index of the speed control loop which is affected by characteristic index of electromechanical system model is analyzed theoretically in this article, and the influence of friction on the time domain characteristic is studied. The influence of friction on the servo system performance is directly analyzed by simulation analysis. According to the simulation result, we can see that when the static friction force is very small and there is little difference between Coulomb friction and static friction, the influence of friction interference on the step response of the system is reflected in the system delay mainly, and the adjustment time of the system has little change;when the gap between static friction and Coulomb friction is large, the step response of the system will be completely changed.
