COMPARISON OF HIGH-GAIN-LINEAR AND SELFADAPTIVE FLIGHT CONTROL SYSTEMS WITH NONLINEARITIES INTRODUCED.

Abstract

The report analyzes the operation of a high-fixed-gain linear flight control system and a self-adaptive system, the MH-96 autopilot. The two systems are simulated on an analog computer for both linear and nonlinear operation. Saturation, backlash, and stiction are introduced, and both systems are found to operate satisfactorily. Using response criteria for high-performance flight vehicles, comparison of the two system designs shows that neither enjoys a clear advantage over the other, but the selfadaptive design is chosen as the preferred system because of its stability under disturbance conditions and its better limit cycle characteristics when backlash is present.
