Refined H/sup infinity / optimal approach to rotorcraft flight control-a simulation on time responses

An approach to refining an H/sup infinity /-optimal controller for the four-block H/sup infinity / control problem is proposed. The H/sup infinity / norm of the sublayers can be improved by this approach. A simulation of the rotorcraft flight control on time responses is provided. The simulation results show promising progress both in the frequency domain and in the time domain without inflation of the McMillan degree of the controller.<
