ANALYSIS OF DYNAMIC CROSS-COUPLING AND DESIGN OF DECOUPLING CONTROLLER FOR CANADIAN SCWR

摘要：

The dynamic relationship between inputs and outputs of the Canadian SCWR is modeled as a MIMO(Multiple-Input and Multiple-Output) system. It is found that the system has high power-to-flow ratioand strong cross-coupling among different variables, which makes the control system design morechallenging. The most appropriate input-output pairings are determined based on the dynamic crosscouplinganalysis on the linear dynamic model in the frequency domain. Subsequently, a dynamic precompensatoris designed to reduce the effects of the cross-coupling using the DNA (direct Nyquistarray) method. Simulations of the closed-loop system have demonstrated that the pre-compensator canindeed simplify the controller design process and lead to improved performance.
