Abstract. A new approach to the problem of rejection of a sinusoidal disturbance of unknown frequency, bias,amplitude, and phase for a nonlinear unstable system with a delay in the control channel is considered. The proposed solution is based on combination of the well-known predictor feedback method with an adaptive scheme which identifies the disturbance frequency.
Keywords: control in delay conditions, predictor, sinusoidal disturbance.
