再入机动飞行器的模糊自适应H2/H∞ 控制

针对再入机动飞行器(MRV)动态的非线性和不确定性，将模糊自适应理论与鲁棒H2/H∞控制理论相结合，提出一种MRV的模糊自适应H2/H∞控制方法。该方法利用模糊逻辑系统逼近导弹模型的非线性函数，补偿其建模的不确定性；并且基于H2/H∞混合优化控制与非零和博弈理论，设计了鲁棒H2/H∞控制器补偿模糊系统的逼近误差和外界干扰，进而改善控制性能，使得性能指标在达到最优化的同时满足H2/H∞性能指标。通过仿真分析，验证了所提出控制方法的有效性。

Fuzzy adaptive H2/H∞ control for maneuvering reentry vehicle

A fuzzy adaptive H2/H∞ control is proposed for a maneuvering reentry vehicle(MRV). The controller consists
of two parts: An adaptive fuzzy controller which is constructed to approximate the uncertain nonlinear function, and a robust
mixed H2/H∞ controller. Based on the mixed H2/H∞ control and the non zero sum game theory, a robust H2/H∞
controller is designed to attenuate approximation errors of the fuzzy system and external disturbance, thus the controller
performance is improved, while the controller possesses a optimal H2 performance index and meets the H∞ performance
index. Simulation studies demonstrate the effectiveness of the proposed controller.
