H/sub /spl infin// control of continuous time fuzzy dynamic systems

This paper addresses robust H/sub /spl infin// control of complex systems which can be represented by an fuzzy dynamic model. A new controller design method using state feedback is proposed based on quadratic stability theory. A number of necessary and sufficient conditions are derived for quadratic stabilizability with disturbance attenuation of the control system concerned. An example is also given to demonstrate the performance of the proposed controller design methods.
