"MIMO Robust Servo Controller Design Using Polynomial Differential Operator"


The multivariable robust servo system controller design problem is one of the most interested problems attracting concern in control engineering field. The servo controller design problem is usually desired to find a controller for a plant to solve the robust servomechanism problem such that the stability of the closed loop system and asymptotic regulation occur, and also other desirable properties of the controlled system are satisfied under existences of disturbance and system parameter perturbation. To solve the servomechanism problem, several researchers have studied by several design concepts. In this presentation, the main result on robust controller is obtained by modifying the well known concept of the internal model principle shown in S. B. Kim et al.[1991] introducing a polynomial differential operator for the state space model and error signal, and getting its extended system. The servo controller can be easily designed by using several kinds of regulator design methods. In order to get the robust controller for the extended system, an existence condition is shown in the view how to get the controllability for the design of the time-invariant feedback control system.
