基于定量反馈理论的火炮随动系统鲁棒控制研究

针对火炮随动系统由于参数摄动及非线性扰动等因素导致控制精度不高的现象，提出一种基于定量反馈理论（QFT）的火炮随动系统鲁棒控制策略。在建立带有不确定参数的火炮随动系统模型的基础上，以某火炮随动系统为例，利用回路整形法设计控制器，分析验证该控制器作用下系统稳定性、跟踪性及鲁棒性，并研究带有参数摄动、输出扰动等情况下系统的时域响应。研究结果表明，所设计的QFT鲁棒控制器能够满足火炮随动系统性能指标要求，有较强的鲁棒性和良好的跟踪性能，证明了该方法的有效性。

Research on Robust Control of Gun Servo System Based on Quantitative Feedback Theory

For the low control precision problem of gun servo system induced by parameter perturbation and nonlinear disturbance factors, a robust control strategy for gun servo system based on quantitative feedback theory (QFT) is proposed. On the basis of gun servo system model with uncertain parameters, a certain gun servo system is taken as an example to show the method process, and the robust controller based on QFT is designed by using loop shaping method. System stability, tracking performance and robustness are analyzed and validated, and the system time domain response with parameter perturbation and output disturbance is studied. The research results show that the designed QFT robust controller can satisfy the performance index of gun servo system, and it has strong robustness and high tracking performance, which proves the effectiveness of the method.
