Block Diagonal Controller Design and Analysis of a Nonlinear Experiment System

A design method of block diagonal controller is presented for a nonlinear cross beam experiment system. The nonlinear mathematical model of a cross beam experiment system is established at first. Based on the theory of exact linearization via feedback, a design method of block diagonal controller composed of inverse solution is presented. A block diagonal controller is designed for the nonlinear cross beam experiment system. The simulation results show that the designed system has strong robustness and rapid tracking performance.
