摘要

由于液压系统的摩擦非线性特性,在位置响应中出现了较大的稳态误差和超调,是典型的关联控制动态实现不完善的问题。在这种情况下,有必要能够有效地利用智能控制器框架。本研究的主要目的是开发一种基于双神经模糊的液压伺服系统控制算法。将神经模糊预补偿器与模糊控制器相结合,提高系统的整体性能。实验结果表明,上述预补偿智能框架可以提高系统的整体性能。

Adaptive neuro-fuzzy friction compensator in servo hydraulic system
Because of the friction nonlinearity characteristic in hydraulic system, high steady state error and overshoot have occurred in the position response as a typical imperfect implementation of associated control dynamic. In this situation, there is a necessity to be able to effectively utilizing the intelligent controller framework. The primary purpose of this research is to develop a control algorithm based on two neuro-fuzzy for a hydraulic servo system. This precompensator neuro-fuzzy combined with fuzzy controller will be implemented to enhance the overall performance. Experiments were carried out and the experimental results illustrated that the above pre-compensated intelligent framework can improve the overall the performance.
