Abstract :
On the basis of steady-state design, mathematical model of closed-loop servo system, by means of a certain degree of simplification, was derived employing dynamics theory. System dynamic performance was analysed using Matlab software, with overshoot of 60.86% and rise time of 0.1284 seconds, implying that system response stability hardly satisfied actual application. Therefore, the original system was regulated with PID controller and simulation results showed that the overshoot was reduced by 94.30% from 60.86% down to 3.47%, effectively improving system response stability.
