液压伺服系统模型参考法自适应控制

A SUMMARY OF MODEL REFERENCE ADAPTIVE CONTROL TO HYDRAULIC SERVO SYSTEMS

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 systems are widely used in morden industry control processes. With the development of science and technology, the better performance characteristics of hydraulic servo systems are demanded. SO, the adaptive control hydraulic servo systems have been developed in order to meet the needs of better performance. The structure, mathematical description and characteristics of the adaptive control system have been introduced in detail in this paper, meanwhile, the application of the model reference adaptive control theory to the hydraulic servo system has also been discussed. In the end, we lay emphasis on the designing skills and steps of hydraulic servo model reference adaptive control system using Popov Superstability theory by giving an example.
