Design and Analysis of a Multivariable, Digital Controller for the A-7D Digitac II Aircraft and the Development of an Interactive Computer Design Program

摘要

A multivariable error-actuated digital tracking controller is developed for the Mach 0.18 flight condition of the A-7D Digitac II aircraft using a singular perturbation method. The design is accomplished and simulated after the development of an interactive computer program named MULTI. The complete designed process is presented; a discussion of the robustness of the control law over a range of flight conditions and the effect of an aircraft flight control surface failure is also included. A more accurate aircraft model is required before further testing is accomplished to study the possibilities of other controller designs. The computer package is available to the engineering community.
