The research of non-linear predictive control based on optimum control

首先设计出基于输出反馈的最优控制 ,在此基础上 ,给出连续域的预测控制设计方法 ,把预测控制参数设计问题简化为积分增益ks、预测时域M、补偿增益km的选择问题。用模型预测替代在最优控制中所必需的多微分环节的作用 ,实现超前调节。给出针对非线性对象的预测控制方法。经仿真研究证明 ,这种方法是合理。

Above all, a new algorithm of optimum control based on output feedback is proposed. Based on it , another new algorithm of simple predictive control is proposed , the design load of which is very small ; Moreover ,a universal method of predictive control to non-linear object has been put forward. Simulation results show the proposed algorithm is reasonable and valid.
