中文摘要: 多变量内模控制具有响应速度快、应用时计算量小、对过程干扰的抑制能力强、鲁棒性强、容易设计鲁棒性和稳定性等优点,但由于目前对非方、约束等没有好的解决方法,在工业中几乎没有什么应用,相关的研究也很少。本项目以大型多变量工业对象的控制为研究背景,开展适用于非方及约束的复杂多变量系统内模控制方法研究,包括以下方面:(1).适用于多变量内模控制器设计的模型描述及辨识方法研究;(2).胖系统、方系统、瘦系统及其相互转换的多变量系统内模控制方法研究;(3).带有控制量及对象输出约束的多变量内模控制方法研究。项目提出了传递函数下基于智能搜索的任意信号多变量系统辨识方法,提出了基于奇异值分解的非方系统内模控制方法,提出了基于区域协调分析的胖、方、瘦系统转换及约束系统多变量内模控制方法。项目的目的是力求解决非方、约束、对象特性和滞后相差大等方面的理论困境,为复杂多变量系统的内模控制提供一个有效的理论解决方案。

英文摘要: Multivariable internal model control has the advantage of rapid response speed, low calculating burden, strong anti-interference ability, strong robustness, easy to design and stability. However, because the multivariable internal model control has no effective methods to solve the control problems caused by the non-square and constrained, the application and the relevant researches almost do not exist in the industry. In this project, we take the control problems for great multivariable industrial objects as the research background and study the internal model control methods that are suitable for non-square and constrained complicated multivariable systems. It includes the following contents: (1) Study on the suitable model descriptions and identification methods to design the multivariable internal model controllers. (2) Research on the methods of the internal model control for fat systems, square systems, thin systems and the conversions among the three systems. (3) Research on the multivariable internal model control methods when the control variables and output constraints exist in the system. Under the transfer function, the project proposes an identification method for multivariable systems with arbitrary signals based on the intelligent search technique. We also develop a novel internal model control me
