摘要
为电液比例系统提供了一个输入输出增量式线性时变模型,采用加权限定记忆回归法来估计模型参数,在此基础上进而提出了一种自适应预测控制方法,并给出了最优控制律。仿真结果表明了该线性时变模型和参数估计算法的可行性,表明该自适应预测控制方法具有优良的控制品质。
An input - output incremental time - varying linear model is proposed for electro - hydraulic proportional systems, and the parameters an; estimated by weighted limited memory regression approach. Subsequently an adaptive predictive control method is put forward, and the optimal control law is given. Simulation results demonstrate the feasibility of the model and the parameter estimation algorithm, and show that the adaptive predictive control method has excellent control quality.
