Abstract

A high-speed microprocessor-based controller and its application to the plasma position in the STOR-M (Saskatchewan torus-medium) tokamak is described. An adaptive control procedure based on a high-speed digital signal processor has been used to improve the controller performance. The fundamental functions of this system are the plasma dynamics modeling, the controller adjustment based on parameter optimization, and real-time feedback control. The performance of this high-speed digital controller is described, and a simulation study is discussed. Plasma position measurement using magnetic probes is described
