Abstract
The demanding requirements of modern fighter aircraft have made the design of a robust, energy-efficient environmental control system (ECS) a major challenge for system designers. Problems associated with conventional design approaches include the lack of analytical models and the use of simplistic single-input single-output (SIS0) design methods for highly complex multivariable systems. This paper presents a design approach that uses the multi-input multi-output (MIMO) linear-quadratic regulator (LQR) method to design an optimal environmental control law for a representative fighter aircraft cockpit. Performance of the LQR control law is enhanced by including integral feedbacks to eliminate steady-state errors. A scheme to approximate the full-state feedback with an output feedback system is also illustrated.
