Abstract :
A hybrid optimization approach is advanced for mitigating actuator saturation effects in model following feedback control as applied to adaptive and reconfigurable flight control systems. The linear quadratic regulator and linear programming paradigms are combined such that a suboptimal tracking control law that does not violate the control constraints can be synthesized in real time
