Flight Control System for the CRCA (Control Reconfigurable Combat Aircraft) Using a Command Generator Tracker with PI (Proportional-Plus-Integral) Feedback and Kalman Filter. Volume 1
Abstract
This research develops an integrated software design package useful in the synthesis of CGT/PI/KF control systems, and uses this software package to design and evaluate a longitudinal flight control system for the Control Reconfigurable Combat Aircraft (CRCA). The software package, called CGTPIKE and built with MATRIXx commands, allows for the synthesis and evaluation of a Command Generator Tracker (CGT) which provides inputs to the system and acts as a pre-compensator, and a regulator with proportional plus integral (PI) feedback which forces the system outputs to mimic the model output. The software also allows the incorporation of a Kalman filter for estimation of the system states. Certainty equivalence can be invoked by adopting the LQG assumptions, thereby allowing the Kalman filter to be designed independently of the CGT/PI controller. The total CGT/PI/KF controller can then be evaluated and the design refined. CGTPIKF is an interactive, menu-driven CAD package which can be used in the development of any CGT/PI/KF control system, regardless of application. A flight control system was designed for the CRCA air combat mode (ACM) entry using CGTPIKF. This control system was designed to force the aircraft to emulate a first order response in pitch rate.
