Abstract :
The real-time computer for controlling and regulating the FNAL (Fermi National Accelerator Laboratory) Main Ring power supplies has been upgraded with a new learning control system. The learning time of the system has been reduced by an order of magnitude, mostly through the implementation of a 95-tap FIR filter in the learning algorithm. The magnet system consists of three buses, which must track each other during a ramp from 100 to 1700 A at a 2.4 s repetition rate. This paper presents the system configuration and the tools used during development and testing
