液压伺服系统在现代工业控制过程中得到了越来越广泛的应用。随着科学技术的不断发展,对液压伺服系统特性的要求也越来越严格,所以近些年来发展了液压伺服系统的自适应控制。本文较详细地介绍了液压伺服模型参考自适应控制(简称MRAC)系统的结构、数学描述及特点。讨论了液压伺服MRAC系统自适应律的不同推导方法。用实例重点介绍了用POPOV超稳定理论设计液压伺服MRAC系统的步骤与技巧。
Hydraulic servo system in the modern industrial control process has been more widely used. With the continuous development of science and technology, the characteristics of the hydraulic servo system are also more stringent requirements, so in recent years the development of hydraulic servo adaptive control system. This paper introduces the structure, mathematical description and characteristics of Hydraulic Servo Model Reference Adaptive Control (MRAC) system in more detail. The different derivation methods of adaptive law of hydraulic servo MRAC system are discussed. Emphases are given to introduce the steps and skills of designing the hydraulic servo MRAC system with the POPOV theory.
