 In this paper, three promising approaches (Cone-Splitting, Polyhedral Annexation and Outer Approximation) are considerably modified in order to enhance efficiency. The first one is a recent algorithm built on a new concept of equilibrium point and a modified version of the outer approximation method. We deal with the advantages accrued when outer approximation, cutting plane, or branch-and-bound methods are used for solving these subproblems. The approach introduces a new polyhedral partition and combines branch-and-bound techniques, outer approximation, and projection of polytopes in a suitable way. These methods range from adaptive uniform discretization methods to outer approximation methods. 更多 Approaches for designning a controller which satisfies all the requirements as stability, transient response and disturbance sensitivity is given in this paper via infinite programming. In the first part, several algorithms such as "outer approximation" and "cut map" are introduced for finding the feasible solution of mathematical programming under functional constraints. The second part devoted to design linear deterministic systems, linear adaptive(with time-varying parameters)systems and nonlinear systems....
