This paper considers the problem of designing robust feedback stabilization
controller for a class of fuzzy systems. Based on piecewise Lyapunov funct
ions, new design techniques for state feedback and output feedback controll
ers are proposed. The resultant controller is robust against measurement an
d modelling perturbations. The design conditions are non-conservative, and
the design process is easy to construct by using commercially supported lin
ear matrix inequalities software packages.
