| Abstract: | Based on the feedback linearization method, two different speed nonlinear controllers of are designed by choosing different output functions, and its performance are studied. Based on the mathematical model of separately excited DC motor and differential geometry theory, state feedback linearization conditions are given. State feedback controller and output feedback controller are designed, and the dynamic response characteristics, the anti-interference ability and stable operation areas are discussed of the two controllers. The results show that, for separately excited DC motor mathematical model, compared to the state feedback hnearization controller, the output feedback linearization controller has a more simple structure, better stable operation and dynamic performance, stronger anti-interference capability, et al. |
