| 摘 要： | 针对多变量系统中前馈解耦效果依赖于系统模型的问题,提出了一种基于前馈解耦的鲁棒控制策略来保证系统参数变化时的解耦效果.针对连续轧制过程中强耦合的板形板厚系统,首先依据经验数学模型设计前馈解耦器,然后对消除耦合影响后的多变量系统设计鲁棒控制器,用多变量鲁棒控制抑制破坏解耦效果的各种不确定性因素的影响.针对实际系统中可能存在的干扰信号进行了抗干扰能力实验,针对系统参数可能存在的不确定性进行了抗参数摄动实验;仿真结果显示了良好的解耦效果,这也说明了该控制策略的有效性.

| Abstract: | In multi-variable systems,performance of feed-forward decoupling depends on system model.Feed-forward decoupling based robust control strategy is proposed to guarantee the decoupling performance when system parameters changing.For combined shape and gauge system in the process of continuous rolling,a feed-forward decoupler is designed based on experience mathematical model,then a robust controller is designed for the decoupled multi-variable system.Multi-variable system control is used to inhibit the influe... |
