Abstract
SUMMARY: A common approach to eliminate steady‐state error between system output and its reference is to incorporate an integrator into the control loop itself. In this paper the self‐tuning controller is analysed when a digital integrator is cascaded with the system. It is shown how this leads to the alternative approach of employing a particular form of the cost function minimized by the controller. The two approaches are not directly equivalent, and this paper deals with the similarities and differences of these two approaches of eliminating zero steady‐state error. It also discusses various forms of cost function specifications for achieving zero error.This publication has 7 references indexed in Scilit:
