A Design of Pole Assignment Control Systems for a Discrete-Time Multivariable Plant with Measurement Noise

Abstract

Recently, a design of model matching and adaptive control systems under the presence of measurement noise is reported by employing a non-minimal order state observer. But this method can be only used for the single-input, single-output plant which is stably invertible. In this paper, it will be shown that the idea is also applicable to the multivariable plant which may not have a stable inverse. Since the proposed method can be implemented by simple calculation, it is adequate for an adaptive control in which the controllers must be calculated on line.
