定量反馈理论（QFT）是一种设计具有不确定性的多变量控制系统的直接而有效的方法。针对现有的QFT设计算法计算量大的缺点,提出了一种改进的设计算法。最后以挠性卫星三轴姿态控制系统的俯仰通道作为设计实例,仿真结果表明了所提算法的有效性和优越性。
Quantitative feedback theory (QFT) is a direct and effective way to design multivariable control systems with uncertainty. In view of the large computational burden of the existing QFT design algorithms, an improved design algorithm is proposed. Finally, taking the pitch channel of the three-axis attitude control system of the flexible satellite as a design example, the simulation results show the effectiveness and superiority of the proposed algorithm.
