Analysis and Research of PWR Instrument Commissioning Based on Simulink

Based on Simulink platform,a mathematical model of the lead lag link,differential unit,arithmetic logic module is built.Considering the specific problems encountered in the debug field work,this model is applied in the analysis of key modules and controller and in the resolving of eddy current problems.The test process dynamic control characteristic is simulated,to analyze the trend of the actual response,and conduct the simulation study and propose the concrete solutions.The actual debugging process proved that the use of simulation technology to find the problem,optimize the control data,and adjust the control strategy is very important for the early detection of problems and to speed the test process,shorten the debug duration and increase the debug quality.
