Nonlinear System Internal Model PID Control Simulation Based on Differential Iterative Algorithm

The utilization of MATLAB instructions and procedures can improve the analysis and designing of complex control system, but the situation is the opposite when testing the control effects of complex control algorithm. In this paper, the method of differential equation iteration is utilized to write the core program of the control system. And then, the simulation of various control algorithms can be done by inserting some programming sentences into this core program. The simulation for a nonlinear internal model control shows the convenience of design process and the effectiveness of control.
