Study on identification modeling method for friction nonlinear servo system

Abstract

Abstract: Based on the importance of accurate modeling for the servo control system in design, a modeling method that the system is mainly affected by the?nonlinear friction?influence is proposed, namely, nonlinear system is linearized through the process that friction compensation is superposed in the identification input signal to offset the effect of friction. The modeling validation experimental results show that the model is correct.

摘要： 针对伺服控制设计时系统精确建模的重要性，提出了一种主要针对受摩擦非线性影响的系统建模方法，即通过在辨识输入信号中叠加摩擦补偿来抵消摩擦的影响，从而实现对非线性系统的线性化处理的建模方法。并通过模型验证实验，证明经过这种处理方法得到的模型准确化程度很高。
