基于误差预报的控制系统综合性能评价

Comprehensive Performance Assessment Based on Error Prediction for Control Systems

在实际工业生产过程中,控制系统的扰动通常是许多不同类型信号的混合体,而且经常遇到设定值改变等多操作模式的情况。为了选择综合随机性和确定性的性能评价策略,提出了一种基于误差预报的控制系统综合性能评价方法。首先提取出控制系统的误差序列,计算其预报值,然后比较两者的方差,得出综合性能指标,最后在TE过程仿真平台上进行了试验验证。试验结果证明了该方法的可行性和有效性。

In practical industrial productive processes,the disturbance of the control system is commonly the hybrid of many different kinds of signals;moreover,multi-operating modes,such as set point variation,are encountered often.In order to select comprehensive stochastic and deterministic performance assessment strategy for control system,the method based on error prediction is proposed.The error sequence of control system is extracted first to calculate their predictive values,and then the variance is compared to obtain comprehensive performance indexes.Finally,experimental verification is conducted on TE process simulation platform.The result indicates that this method is feasible and effective.
