Research Abstract

In this study continuous-time adaptive control law was first derived for an elecrto-hydraulic servo system. By linear approximation technique dynamic characteristics of the adaptive control system were analyzed. A parameter which has close relation to transient response after starting of the adaptive control was obtained. A computer aided design technique with the parameter was proposed and a program for designing an adaptive controller was made. By use of the program, an electronic circuit of an adaptive controller was designed and made of analog multipliers and operational amplifiers, etc.. Urther, an electro-hydraulic servo mechanism was constructed with a highspeed type servo valve. Using the analog adaptive controller, performance of the adaptive control system was examined for many kinds of input signal, for example a sine wave and a rectangular wave. It was demonstrated that the adaptive control system shows stable dynamic characteristics to input signals of high frequency up to 80 Hz. It is not easy for a digital adaptive control technique to obtain such a high speed of response. From analytical and experimental study of an analog adaptive controller, a design technique was established and a good performance of the adaptive control system was demonstrated.
