Abstract

An easily implemented digital control method based on a discrete-time process model has been extended to encompass many process types found in common industrial control problems. The system uses a controller and observer based on finite-time settling design; the controller and observer gains are computed directly (noniteratively) from the process model parameters. A softening filter which preserves the finite-time settling behavior of the closed loop system has been developed to minimize manipulated variable excursions.
