%X A model-free compound controller design method is proposed to meet the requirement of a flight simulator in a wide range of frequencies. In addition to the quantitative feedback theory, we employ the feedforward control to make a tradeoff between the strict requirements of the amplitude-frequency characteristic and the phase-frequency characteristic of the flight simulator. In the controller design, the system uncertainties are determined from the power spectrum estimation. The requirement of the amplitude-frequency characteristic of the flight simulator is converted into the tracking specification bounds of the quantitative feedback theory; the requirement of the phase-frequency characteristic is fulfilled by the compensation of the feedforward controller. Simulation results indicate that the proposed method realizes the desired control over a wide of frequencies. Also, this method is model-free and transparent in the design.
