| 摘 要： | 针对热连轧厚度控制系统模型(AGC),提出基于线性矩阵不等式的多目标鲁棒预测控制算法,有效处理了液压厚度控制系统的参数不确定性、扰动以及约束等问题. 由于所得结果以非线性矩阵不等式形式给出,采用锥补线性化思想将控制器的设计转化为一个受线性矩阵不等式约束的非线性规划问题,求解线性矩阵不等式,根据其可行解构造控制器,实现系统的多目标优化控制策略. 仿真结果表明,该方法有效并具有较好的控制性能.

| Abstract: | In this paper,a class of uncertain discrete input-delay system model is investigated based on automatic gauge control (AGC) in hot strip rolling with input constraints, structure uncertainty and disturbance. Based on the hydraulic automatic gauge control and the multi-objective robust model predictive control algorithm, robust model predictive controller is constructed. The cone complementary linearization idea is then employed to convert the controller design into a nonlinear programming problem with linear matrix inequality (LMI) constraints. Finally simulation results illustrate the effectiveness of the proposed methods. |
