研究了非线性不确定系统的概率鲁棒控制问题。针对具有可反馈线性化标称系统的一般系统，提出了一种随机鲁棒性和动态逆相结合的方法。本文将随机鲁棒非线性控制方法应用于高度非线性的复杂飞机模型--高冲角研究模型（HHH-R）。该模型解决了一个大迎角的增强手动控制问题。飞行控制系统的目的是在不使用增益调度的情况下，在规定的飞行包线内提供良好的操纵品质，并对模型的不确定性提供鲁棒性。所提出的随机鲁棒非线性控制探讨了非线性飞行控制逻辑的直接设计。因此，最终设计考虑了飞机高保真仿真模型中所有重要的非线性。控制器参数的设计，以尽量减少违反设计规范的概率，这提供了良好的鲁棒性的稳定性和性能的设计模型的不确定性。目前的设计与早期的控制器相比，产生了一个基准设计竞赛。
This paper considers probabilistic robust control of nonlinear uncertain systems. A combination of stochastic robustness and dynamic inversion is proposed for general systems that have a feedback-linearizable nominal system. In this paper, the stochastic robust nonlinear control approach is applied to a highly nonlinear complex aircraft model, the high-incidence research model (HIRM). The model addresses a high-angle-of-attack enhanced manual control problem. The aim of the flight control system is to give good handling qualities across the specified flight envelope without the use of gain scheduling and also to provide robustness to modeling uncertainties. The proposed stochastic robust nonlinear control explores the direct design of nonlinear flight control logic. Therefore, the final design accounts for all significant nonlinearities in the aircraft's high-fidelity simulation model. The controller parameters are designed to minimize the probability of violating design specifications, which provides the design with good robustness in stability and performance subject to modeling uncertainties. The present design compares favorably with earlier controllers that were generated for a benchmark design competition.
