This paper presents a new concept for solving fuzzy controller stability problems on matrix inequalities via evolutionary computation (EC). Gain scheduling problem of a multi-model fuzzy system, which satisfies the Lyapunov stability criteria, is solved. The generalized eigenvalue problem (GEVP) can be directly introduced into EC in searching positive definite (PD) or positive semi-definite (PSD) matrices, by making a penalty for an individual, that violates the inequality condition in order to solve the nonlinear constraints or linear matrix inequalities (LMIs). Examples for illustrating the proposed methodology are taken into consideration and the results show the effectiveness.
