Robust Tracking Control Based QFT and Pade Approximation for Flight Simulator
A new design technique based QFT and Pade Approximation for tracking control has been proposed. QFT controller attempts to place all plant poles within a specified region on the s-plane to guarantee the desired closed loop performance. As for the robust dynamic tracking performance, a new algorithm to design the feedforward controller based pade approximation has been prescribed in the case that the preview information of the desired output is not available. Simulation results for flight simulator show that the proposed approach is effective, successful and applicable.
