Abstract :
It is well-known that tracking and regulation control objectives can be achieved independently. This paper focuses on the synthesis of the feedforward part of a two-degree-of-freedom LPV/LFT controller. Here, the feedforward filter synthesis, which includes a constraint on the control signal, is cast as an L2 full-information minimization problem. The effectiveness of the proposed approach is demonstrated on the design of an LPV/LFT missile autopilot.
