Ion cyclotron resonance heating(ICRH) is one of the most important auxiliary heating methods on the EAST. In response to the rapid change of load under the circumstance of a plasma discharge, improving the capacity of the high power and steady state operation of ICRH system, this paper proposes a design of ferrite fast impedance matching measurement and control system based on the CompactRIO embedded development platform and the LabVIEW graphical programming software. This paper elaborates the overall design framework of the system and the implementation methods and functions of software and hardware design. Tests show that the system can respond to the rapid change of load in time to generate control voltage signal, control ferrite to make real-time response, and meet the requirements of real-time, stability and effectiveness of the system.
