摘要
以系统的纯迟延作为先验知识,通过分离与重构系统误差的随机性和确定性分量,分别计算热工控制系统随机性和确定性性能指标,分析了多类扰动下的系统综合性能评价问题。并利用某电厂实际的正常运行数据对研究的结论进行了验证。结果表明,所提出的评价方法客观地反映了控制系统的实际运行状态。
In this paper,the system pure delay as a priori knowledge,through the separation and reconstruction of the random and deterministic system error component,we calculated the thermal control system of random and deterministic performance,analysis of many types of system disturbance comprehensive performance evaluation.And the actual use of the normal operation of a power plant on the findings of the study data were verified.The results show that the proposed evaluation method to objectively reflect the actual control system running.
