Abstract : Adaptive sample-data control of time-varying bending modes of a flexible airframe is analyzed. Adaptive control is achieved by variation of the sampling rate in conjunction with a fixed digital compensator. Means for the identification of the bending modes are conceived and analyzed. Simulation results of the adaptive control scheme are shown to verify the adaptive control technique. (Author)
