Abstract :
It is shown that sliding mode control is equivalent to feedback linearization with an appropriate choice of desired output dynamics. It is this equivalence that leads to the development of a control command limiting algorithm that provides actuator saturation protection for input/output feedback linearizable systems with more inputs than outputs. The command limiting algorithm is integrated with an optimal control redundancy algorithm to form a complete control allocation method. The control allocation minimizes control effector deflections for control redundant situations and limits control commands for control deficient situations. The control allocation method is applied to a tailless fighter aircraft model
