Abstract
This paper presents an application of a self-tuning regulator to the control of a known amount of granules from a hopper. Generally, there are many kinds of stochastic disturbances in processes handling granules. For such processes, it is difficult to obtain a good performance by using conventional control methods. Therefore, we attempted to apply the self-tuning regulator to the process. In order to do this, it was necessary to have models of the process dynamics and of the disturbances. First, modeling of the disturbances is discussed, and the self-tuning algorithm is applied to our process. As for the results, it is shown that the self-tuning regulator is more robust and is very useful for processes handling granules.
