Abstract [en]

One issue to be dealt with when designing flight control laws is how to deal with actuator redundancy. While traditional aircraft use elevator, aileron, and rudder to control the aircraft motion in pitch, roll, and yaw, modern aircraft may have ten or more control surfaces that can be independently controlled. Two tools for distributing the control effect among a set of actuators are linear quadratic regulation and control allocation. In this paper we investigate the relationship between these two design tools and show that in some cases they can be tuned to give the exact same control signal.
