摘　　要：压水堆的安全性会受到控制性能和扰动的影响,为了及时检测控制器的控制性能,避免整个系统的崩溃,基于输出分布控制(output distribution control,ODC)理论,提出了一种在线控制性能评价系统。系统采用基于巴氏性能指标的性能评估方法,提高了性能评价的准确性和敏感性。并考虑了实时I/O数据和历史I/O数据的概率分布,利用滑动窗进行输出概率分布的更新,增大性能指标统计数据的范围。仿真结果表明,该在线控制性能评价系统对于控制效果的波动有准确的判断,同时也能排除控制过程中的非高斯扰动,避免影响性能评价。The safety of pressurized water reactors is affected by the control performance and disturbances.In order to detect the control performance of the controller in time and avoid the collapse of the whole system,an online control performance evaluation system is proposed based on the output distribution control(ODC)theory.The system adopts the performance evaluation method based on Bhattacharyya performance index,which improves the accuracy and sensitivity of performance evaluation.Secondly,the probability distribution of real-time I/O data and historical I/O data is considered,and the sliding window is used to update the output probability distribution,which increases the range of performance index statistics.The simulation results show that the online control performance evaluation system can accurately judge the fluctuation of control effect,and also eliminate the non-Gaussian disturbance in the control process to avoid affecting the performance evaluation.
