Abstract: This paper analyses the dry process of a drum dryer and Suggests a first-order lag system model with varying time delays and measurable disturbance, which accurately agrees with the operating mode. In terms of the problems of this system, appropriate methods are used to carry out the principls of self-tuning regulator (by K. J. Åström and B. Wittenmark, in 1973) and to form an adaptive regulator with feedforward compensation and varying time delays tracing used on drum dryer system. Simulation results show that the control algorithm is available.
