This hybrid simulation demonstrates the feasibility of using a digital computer for the realization of a discrete filter-controller to drive a 3"/50 gun mount in response to step, ramp and stabilization orders. The gun position designation signals are subject to random environmental noise and the observation of position is contaminated by random measurement noise. These noise sources are assumed to esmibit a normal distribution with zero mean. A filter is used to predict plant position and velocity from a noisy observable position, and a controller is used to provide the desired feedback of these states for a ripple-free response. The simulation results indicate that there is no detectable difference in response between constant filter gains and adaptive filter gains for this time-invariant plant. The results also demonstrate that the application of good programming techniques is paramount in minimizing the timing and scaling limitations imposed by hybridization.
