Abstract :
This paper presents the design of switched feedback controllers for load factor tracking. The controller consists of a discrete set of state feedback gains which are switched according to some system states such as Mach number and altitude. Attention is restricted to the design of a longitudinal controller for the ADMIRE fighter benchmark model. Each state feedback gain is designed to track the load factor, nz, where integral action is added to enforce zero steady state error. The stability of the overall closed-loop system is established thanks to piecewise linear quadratic Lyapunov functions and dwell time theory.
