摘要
This paper is concerned with the practical application of model reference adaptive control (MRAC) on the position control of a hydraulic cylinder. In this study, the modified hyperstable-MRAC method is employed to adapt the loading effect. The reference model is based on the reduced-order model of the plant, which is derived by using the Routh stability criterion and the Pade approximation technique. A 16-bit microcomputer is used to design an adaptive controller. The experimental results are also compared with those obtained by using the classical control theory.
