Abstract

Abstract : This paper deals with the control of the ball position on a beam using hybrid arrangement of iterative learning control (ILC). If the process to be controlled is an under-actuated, unstable, nonlinear, and double integrating one, the conventional controllers are not able to control the system adequately. To overcome this problem, the ILC strategy is coupled in series with the conventional control scheme, thereby stabilizing the process with better convergence. The proposed hybrid LIC (HILC) strategy is embedded in the existing control loop. A real-time implementation of the proposed control technique is carried out and its performances are analyzed.
