DUAL MODE CONTROL
Abstract
A simple compensation scheme for the control of a process is presented. The criteria are that the process output closely approximate the process input when the latter is a step and that there be no steady state error. The reference process chosen is that of chemical concentration control. Employing a compensation block with pure gain gives a fast response that has a steady-state error. Integral compensation eliminates the steady-state error, but its response has a very sluggish transient character. A switching arrangement is evolved that combine the desirable characteristics of both types of compensations while removing the unwanted traits. This configuration is set up on an analog computer and compound results which satisfy the original criteria are empirically obtained for a plant of three poles. This is done for plants of two poles and one pole with equal success, exhibiting the validity of the technique for a general plant.
