Aerospace Instrument-Making Annotation << Back EVALUATION OF THE QUALITY OF FLIGHT CONTROL OF AN AIRCRAFT CARRIER-BASED AIRCRAFT USING THE CRITERION OF THE DEGREE OF CONTROLLABILITY Chzhan Lifey An algorithm has been developed for controlling an aircraft carrier-based aircraft at the approach and landing stage using a linear quadratic controller. The analysis of the degree of controllability of the state variables of aircraft with different weights is carried out. The control accuracy and control quality at different weights of the aircraft are shown. A criterion of the degree of controllability of state variables is proposed, which allows us to evaluate the control characteristics not only for the entire system, but also for all components of the state vector. Keywords: carrier-based aircraft; degree of controllability; controllability; linear quadratic controller; flight control quality; landing on an aircraft carrier.
