摘要
文章针对被动式电液伺服加载系统研究中存在的问题,提出了“有前馈可测扰动项的广义最小方差自校正控制”(FD-GMV)。文中着重分析了控制权Q对自校正性能的影响,讨论了Q的几种选择方案。根据算法的特点,提出了一种能有效降低起始超调的简便方法,同时也避免了起始控制失调现象。实验结果十分令人满意。
To deal with the problems in the study of passive electrohydraulic servo loading system,a self-tuning control algorithm(FD-GMV) is proposed in this paper.The effect of the control weighting Q on selftuning performance is analysed. Alternative ways of Q are discussed. Based on the characteristic of the algorithm, an effective method is given so that the initial overshoot during the self-tuning course could be reduced obviously or the control detuning phenomenon could be eliminated. The result is very satisfactory.
