Techniques for the design of control systems for manually controlled, high-performance aircraft must provide the following: 1) multi-input/multi-output solutions, 2) acceptable handling qualities including no tendencies for pilot-induced oscillations, 3) performance and stability robustness in the presence of significant plant uncertainty, 4) minimum performance degradation in the presence of actuator saturation (particularly rate saturation), and 5) a tractable approach for compensator design. A design technique built upon quantitative feedback theory is offered as a candidate methodology that can provide flight control systems meeting these requirements and that does so over a considerable part of the Eight envelope. An example utilizing a simplified model of a supermaneuverable fighter aircraft demonstrates the proposed design methodology. References: 19
