| 英文摘要 |
| A fuzzy control system for continuous-time nonlinear systems is presented, which is based on fuzzy dynamic model; The stability of the closed-loop fuzzy system is analyzed. Then systematic procedure to design fuzzy controllers is formulated. A sed of local linear models are linked together by fuzzy membership function to obtain the continuous global model. By considering the fuzzy system as a set of nominal linear systems subject to perturbations contributed by other interacting subsystems, a sufficient condition for the stability of the closed-loop fuzzy system is derived via the concept of vector Lyapunov function. The validity of the fuzzy model based control technique if illustrated by a simulation example. |
