| Summary: | 碩士 === 中華技術學院 === 電子工程研究所碩士班 === 94 === In the thesis, the conventional PD, PI, PID controllers integrated fuzzy theory are proposed, the fuzzy theory is used to tune the gain parameters of each proposed controller, so that the tracking problem can be solved in a class of nonlinear systems. The control laws of the proposed controllers (fuzzy PD, PI, PID controller) are respectively used to approximate an ideal control for nonlinear systems. In addition, a compensated controller is designed to assure the system stability. The control laws of the proposed controllers are derived from the Lyapunov stability analysis, so that the system tracking ability and the error convergence can be guaranteed in the closed-loop system. Finally, four nonlinear systems, an oscillation system, an inverted pendulum system, a Ven-Der-Pol system and an electric drive system, are respectively utilized to show the satisfactory performances of the proposed control schemes. Finally, the proposed control algorithms are realized by NIOS embedded system chip, then applied to DC motor speed control.
