Experimental results on a self-tuning control scheme

A self-tuning control scheme that is suitable for enhancing system performance in the presence of variations in operating conditions is proposed. Unlike most of the existing self-tuning control strategies, the proposed scheme makes use of a linear combination of two signals as the variable of a discrete-time model chosen to describe the system dynamics. This approach enables the system performance to be enhanced without increasing the computational time required. Experimental studies involving the control of a DC servo motor shows that the proposed scheme is effective
