Abstract

With a rapid development of the digital signal processor in recent years, a full digital control system for the superconducting section of APT is designed and implemented by using TI´s C6x processor. A digital control system is first modeled and simulated using Matlab/Simulink. Simulation results confirmed the feasibility and flexibility of the digital control system for LLRF feedback system. Due to flexibility of DSP, different control algorithms are implemented and compared in the system. Particular attention is paid to the inherent pipeline delay problem associated with a digital control system and its effect and limitation on the overall system performance
