Abstract: The design of a H dynamic output feedback controller, satisfying the configuration of closed-loop poles was studied for a class of uncertain T-S fuzzy dynamic systems, via linear matrix inequalities (LMIs). The control laws are in the form of so-called dynamic parallel distributed compensation (DPDC) which is essentially for the design of nonlinear dynamic feedback controllers. Such a design is more general than previous ones since the parameter uncertainties in controlled output variables and the non-zero control coefficients of controller are both taken into account. Then, the sufficient condition is given to the global stability of closed-loop fuzzy systems with the condition transformed into LMI form. The effectiveness of the proposed approach is successfully verified through an example of complex nonlinear Chen's system by means of the numerical simulation.
