1. A control system comprising: an actuator for positioning a control surface; a control law for controlling the actuator, and a processor for generating an output vector to direct the control law, the processor comprising: an open loop module for generating the output vector as a function of a state vector and an input vector; a corrector for generating a corrector vector as a function of the output vector; a comparator for generating an error vector by comparing the corrector vector to the input vector; and an estimator for generating the state vector as a function of the error vector, such that the error vector is minimized.
