Abstract
Abstract This paper is concerned with disturbance rejection of multivariable Smith predictor control for multiple-delay systems. The Smith predictor control method can convert the delay control problem to the delay-free one, and yield desired responses to the reference inputs. However, if the process is subject to unmeasurable disturbances, the error decay can not be made as fast as desired. Particularly, if the process has poles near the origin in the complex plane, the output responses may be sluggish enough to be unacceptable. A new method which can yield zero steady state error and desired transient responses to the disturbances is proposed.
