Application of SIMULINK in Non-linear System Analysis

This paper proposes using the SIMULINK toolbox in Matlab to analyze and check the nonlinear control system.According to the non-linear system mathematical model,SIMULINK toolbox can be directly used to build simulation model and proceed with the simulation study.This method can flexibly change the system structure and parameters,making the non-linear system performance analysis very simple and convenient;the analysis of system response curve helps to point out the way of improving the performance function of non-linear control system.
