Firstly, a mathematical model of MIMO system is established, and the appropriate controller structure is selected according to the characteristics of the system. Then, a robust adaptive controller based on fuzzy approximator is designed, and the parameter uncertainty in the controller is compensated. Finally, the designed controller is verified by MATLAB/Simulink simulation platform, and compared and analyzed with traditional control methods. The simulation results show that the robust adaptive controller based on fuzzy approximator has good robustness and adaptability, can effectively control the performance indicators of MIMO system, and can be applied in practical engineering.
