本文研究了处于控制领域前沿的鲁棒控制理论，对其中的线性二次型高斯控制理论和H_∞控制理论进行了深入的研究与分析，进行了一定的理论推导，并得出了这两种控制理论在实际系统中的运用方法。本文针对宏观经济系统和大气污染控制系统模型的不确定性，分别运用线性二次型高斯控制理论和H_∞。控制理论进行宏观经济系统和大气污染系统的的分析与控制，消除系统中的模型化误差及其本身和外部的扰动信号等不确定性的影响，借助MATLAB设计软件进行仿真，得出最佳控制策略。对于宏观经济系统可以合理地运用财政和货币这两大经济杠杆，从而能够保持宏观经济系统的稳定性并且可以准确跟踪并达到预先给定的各项经济指标。对于大气污染系统采用最佳污染实施控制策略，使得大气污染系统能够保持鲁棒稳定性并且规定的指标始终在期望目标值内运行。
This paper study the theory of robust control, which is located in the top of the field of the control. It is deeply study and analyze the theory of Linear Quadratic Gaussian control and the theory of H∞ control which include in the theory of robust control, and infers some theory in detail, and gets the using method of the two theories in the fact systems. This paper aims at the uncertainty of the macroeconomic systems and atmospheric pollution system which is analyzed and controlled by the theory of Linear Quadratic Gaussian control and the theory of H∞ control, and avoids the effect of the modeling error in systems and the disturbed signal from the system and outside. By using the MATLAB software to simulate, we can get the optimal control strategy. The macroeconomic systems can keep the stability and is exact traced and obtained the guideline which have been given by using the policy of finance and currency in reason. The atmospheric pollution systems can keep the robust stability and the regulated guideline of the systems run in the expectation guideline.
