Abstract
The Total Energy Control System (TECS) is a method to control airplane longitudinal
flight dynamics by regulating energy and energy balance. This multiple input, multiple output
method accounts for the highly coupled nature of aircraft dynamics and allows for control of
airspeed and altitude with a proportional-integral controller. This paper reviews the heuristic
TECS control law and then validates it in a MATLAB simulation. Next, an adaptive TECS
is designed by augmenting the fixed-gain controllers in a nominal TECS with retrospective
cost optimization-based adaptive controllers. It is shown through simulations that adaptive
augmentation improves the closed-loop performance and accelerates the tuning process.
