## Abstract

Control system design is the task of finding a controller which satisfies prescribed specifications, under a given set of constraints. Desirable controller parameters must satisfy a certain set of identities and inequalities that represent the plant dynamics, constraints and specifications. Hence, control system design amounts to solving a set of equations subject to inequality constraints that contain the controller parameters as unknowns. Since the given set of equations and inequalities is often very complicated and not precisely known, a solution should be found by a cut-and-try method guided by intuition and experience, which has been a major tool of practical control system design.
