7Marco Muenchhof and Tarunraj Singh: Concurrent Feed-Forward/Feed-Back Controller Design Using Time Delay Filters. Proceedings of the AIAA Guidance, Navigation and Control Conference, American Institute of Aeronautics and Astronautics, 2002. Language: Englisch
This paper discusses the concurrent design of a feedforward time-delay filter and a linear state feed-back controller. The optimization is carried out using a quadratic cost functional which weights both, disturbance rejection and control tracking performance. A minimax optimization scheme is employed to achieve robustness with respect to parameter deviations. Analytical gradients are provided for the cost function. This information can be exploited to expedite convergence of the optimization procedure. The proposed technique is illustrated on the Floating Oscillator benchmark problem.
