Robust discrete controller design for an unmanned research vehicle (URV) using discrete quantitative feedback theory

The application of non-minimum phase omega '-plane discrete MIMO (multiple-input-multiple-output) quantitative feedback theory (QFT) to the design of a three-axis rate-commanded automatic flight control system for a URV is presented. The URV model used is a seven-input three-output state-space...

Summary:The application of non-minimum phase omega '-plane discrete MIMO (multiple-input-multiple-output) quantitative feedback theory (QFT) to the design of a three-axis rate-commanded automatic flight control system for a URV is presented. The URV model used is a seven-input three-output state-space system derived from the small-angle perturbation equations of motion. The controllers and prefilters designed provide a three-axis noninteracting rate-commanded automatic flight control law implementation on the Lambda URV. Hybrid nonlinear simulations verify the successful application of discrete QFT. The yaw-rate channel meets all specifications.< >
