Abstract

The front end (FE) control was recently reported as an alternative solution to a class of set-point control problems. Initial experiments with a pneumatic pick and place robot arm showed that FE control has a distinct advantage over conventional set-point control in achieving a high quality of system response in terms of time domain specifications. This has motivated further applications and analysis of FE control systems. This paper presents an adaptive FE control scheme for a class of time-delayed systems having unknown gains. The proposed scheme, when employed in controlling a repetitively operated thermal process, exhibits appreciable improvements in the quality of response compared with the conventional on/off adaptive control scheme.
