TL;DR: A new process-model control system which can yield zero steady-state error and desired transient responses to step disturbances and arbitrary initial conditions is proposed.
Abstract: This paper is concerned with linear systems containing time delay in control. A process-model control which utilizes a mathematical model of the process in the minor feedback loop around the conventional controller to overcome delay is developed. A new process-model control system which can yield zero steady-state error and desired transient responses to step disturbances and arbitrary initial conditions is proposed. The remarkable feature of the proposed system is that the states of the model and the integrator are unobservable in the output of the model. It is shown that this structural property is the key by which the major problems of process-model control can be solved.

TL;DR: In this article, an observer which can estimate a linear function of the state of the system is proposed for the purpose of implementing a feedback control law, and the relation between the observer and the Smith predictor is also discussed.

TL;DR: In this article, a disturbance rejection of multivariable Smith predictor control for multiple-delay systems is considered, and a new method which yields zero steady state error and desired transient responses to the disturbances is proposed.

TL;DR: The time optimum control of the experimental system as well as PID control is used to demonstrate the effectiveness of the method, and an extension of Smith's method is used.
