摘　　要：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。The quantitative feedback theory (QFT) is a direct and powerful design method for multivariable control systems with plant uncertainties. An improved QFT method is suggested in this paper, based on the investigation of the present method which has the disadvantage of a great amount of calculation. Finally, as an example, the pitch loop of the three-axis attitude control system of a flexible satellite is designed using the improved QFT method given. The simulation results verify the efficiency and the advantage of the improved method.
