The effect of design parameters on the tracking performance of high-gain error-actuated controllers

The effect of varying the primary design parameters when designing noninteractive high-gain error-actuated controllers for tracking systems was studied. To obtain a physically realizable controller design it was critical to obtain slow but decoupled output response. This was done through properly calculating the transducer matrix and properly selecting the values of the fast modes. The effect of varying other design parameters, such as the asymptotic values of the slow modes and the scalar gain parameter, was also studied. The controller designed was shown to be robust to plant parameter variations. The data from a recent advanced fighter aircraft was used to illustrate the results.
