Abstract: A new control system design scheme is proposed in this paper on the basis of given system controller structure. The scheme can make the designed control systems possess expected dynamic and static performances by using parameter optimization technique. It overcomes the demerit of most known control system design schemes which are not directly related to expected system performances, and avoids making trial and error many times to achieve expected performances. Moreover, the scheme allows system models to contain nonlinear characteristics. An expert system scheme for determining system controller structures is also provided . The given example demonstrates the practicality of the scheme.
