提出了一种输出反馈的H∞预览控制器。在本研究进行的飞行控制操作中，由观测器估计干扰输入，并使用H∞预览控制器对干扰响应进行预测和限制。将该系统应用于一架用于研究火箭飞机飞行控制的实验无人机（UAV）的纵向动力学中。通过飞行试验验证了预估扰动的准确性和预估控制器的性能。试验结果表明，基于俯仰力矩扰动模型的系统可用于实验无人机的飞行控制。
An output-feedback H∞ preview controller is proposed. In the flight control operations performed in this study, the disturbance input is estimated by the observer, and the disturbance responses are predicted and restricted using the H∞ preview controller. The proposed system was applied to the longitudinal dynamics of an experimental unmanned aerial vehicle (UAV), which was developed to study the flight control of rocket planes. The accuracy of the estimated disturbance and the performance of the preview controller were validated through performing flight testing operations. From the results of the flight testing operations, the proposed system based on the disturbance model of the pitching moment can be used for the flight control of the experimental UAV.
