Abstract

The invention aims to improve the control accuracy of a servo system and provides a neural network model reference adaptive control method applied to the servo system. The nonlinearity of the servo system is effectively compensated, the interference is suppressed, and the tracking accuracy and robustness of the servo system are improved. In addition, the control of the servo system is not needed to be constructed on the basis of accurately modeling an object, the modeling cost is saved, the method is easily implemented in engineering, and the cost is reduced.

Description

technical field [0001] The invention relates to a neural network-based servo control system and method. technical background [0002] The servo system is a complex electromechanical control system, and its essence can be regarded as a position closed-loop control system driven by a motor, which plays an important role in national production and national defense construction. Because it occupies a very important position in various fields, the requirements for its performance are constantly increasing, especially in cutting-edge fields such as national defense, military and aerospace. It can be seen from the general development trend of servo systems at home and abroad that "high response, ultra-low speed, and high precision" are its main development directions. Among them, "high frequency response" reflects the ability of the servo system to track high-frequency signals, that is, the system's tracking ability when the position command signal is constantly changing. "Ultra-...
