| Abstract: | A simulation model of a certain servo system is established with Matlab / Simulink, and the performances of the system are analyzed. The unit step response curve of the system is deduced with the simulation model established by Simulink, and then the stability of the system is determinated according to its unit step response curve. When the performance of system can not meet the required performance indexes, the system performance can be improve by adjusting the system parameters and adding a compensator. It indicates the results of convenient and flexible dynamic simulation. The results show that the method to analyze automatic control system by the aid of Matlab / Simulink is simple, fast and efficient. |
