摘要

描述了线性和非线性飞机动力学下自适应飞行质量控制系统的综合和稳定性评估的分析过程。该程序直接将所需的低阶等效系统(LOES)频率和阻尼参数值整合到控制律的合成中，以提供对MIL-STD-1797A指南的最佳遵守。应用该程序推导了某型战斗机的纵向控制律。给出了仿真结果。据信，这种方法提高了飞行质量，可能适合于减轻飞行员引起的振荡问题，因为它的闭环相位滞后基本上是LOES规范的相位滞后。

Analytical control synthesis for adaptive flying-qualities adherence

An analytical procedure is described for synthesis and stability assessment of control systems for adaptive flying-qualities adherence with linear and nonlinear aircraft dynamics. This procedure directly incorporates desired low-order equivalent system (LOES) frequency and damping parameter values into the synthesis of control laws that provide optimal adherence to MIL-STD-1797A guidelines. The procedure is used to derive a longitudinal control law for a contemporary fighter aircraft. Simulation results are presented. It is believed that this approach offers improved flying qualities and may be suitable for mitigation of pilot induced oscillation problems because its closed-loop phase lag is essentially that of the LOES specification.
