H/sub /spl infin// control of uncertain dynamical fuzzy discrete-time systems

A new kind of dynamical fuzzy model is proposed to represent discrete-time complex systems which include both linguistic information and system uncertainties. A new stability analysis and control system design approach is then developed for this kind of dynamical fuzzy model. Furthermore, a constructive algorithm is developed to obtain the H/sub /spl infin// feedback control law. An example is given to illustrate the application of the method.
