APPLICATION OF THE FAST ARRAY PROCESSOR FOR JT-60 PLASMA CONTROL

Improvements of faster and more accurate computation in the JT-60 feedback control system are required for control of high beta plasmas which are produced in the additional heating experiment. This paper reports how we design its upgrade control system. The feedback control system is modified to be a multi-step pipelined system which is composed of two minicomputers for control calculation and a fast array processor, which calculates the state variables such as plasma position and shape prior to the control calculations.
