Investigation of Disturbance Accommodating Controller Application to a Missile Autopilot.

Abstract

The Disturbance Accommodation Controller (DAC) uses a combination of waveform-mode disturbance modeling and state-variable control techniques. This approach permits three primary modes of disturbance accommodation: cancellation (absorption) of disturbance effects, minimization of disturbance effects, or constructive utilization of the disturbances as an aid in accomplishing the primary control task. It is possible to minimize the effects of the disturbances modeled in this report by use of DAC techniques. It is also possible to combine two separate DAC's designed for disturbances at different places in the plant, into a functioning unit which would still perform its overall purpose. However, the true test of how a DAC would function in a system application would be to implement one in a 6-DOF simulation and fly it with a severe program of varying disturbance vectors. (Author)
