H∞ control of uncertain fuzzy continuous-time systems

A new kind of dynamical fuzzy model is proposed to represent the continuous-time complex system which includes both linguistic information and system uncertainties. A new stability analysis and control system design approach is developed for this kind of dynamical fuzzy model. Since the fuzzy model considers the norm-bounded disturbance the controller design problem becomes a H-infinity control problem. A constructive algorithm is developed to obtain the H-infinity feedback control law. Finally, an example is given to illustrate the application of the method. (C) 2000 Elsevier Science B.V.
