带有跟踪微分器的无模型自适应控制方法研究
Research on model-free adaptive control method with tracking differentiator
摘要
Abstract
With an aim to solve the problem that the basic M FAC (model‐free adaptive control ) method has had a poor control performance for a class of SISO nonlinear system with measure‐ment disturbance , the tracking differentiator (TD ) in the active disturbance rejection control (ADRC) is added to the model‐free adaptive control as a feedback filter so that a kind of new method for enhancing the ability to suppress interference is suggested .This method first makes the measured signals filter through the tracking differentiator of the feedback channel and then seek for the differences with given signals to obtain the error signals for carrying out control , whereby effectively suppressing the interference brought about by the measurement .Thus far , better output performance are obtained and the robustness of the model‐free adaptive method has been improved .T he simulation results verify the effectiveness of this method .关键词
