Abstract :
A method for the design of a self-tuning controller (STC) for a single-input nonminimum-phase system with unknown or varying time-delay is proposed. First, an improved parameter estimation algorithm is given. It uses one of two adaptive control blocks according to the estimated results. When the dead time of the plant is unknown or changing, the STC is structured as a self-tuning Smith predictor. The validity of the proposed method has been investigated by numerical simulation
