摘    要:将预测控制可达性基准推广到了具有可测扰动的控制回路,得出了预测控制前馈-反馈可达性基准。它可以作为对可测干扰的预测控制回路监控和评估的基准,并和其他基准联合使用对控制回路进行监控,得出前馈的加入对系统性能的影响程度;根据此基准可以构造多种形式指标对性能进行监控。

关 键 词:可测干扰  预测控制  性能监控  子空间辨识

Abstract:In this paper, an MPC feedforward and feedback (FF-FB) achievable benchmark was used to assess the performance of MPC loops with measued disturbance, which was an extention of the MPC-achievable benchmark. It can be used together with MPC-achievable benmark to analyse the output variance and determine the potential benefit if the feedforward control was implemented; a simulation using this benmark to assess and monitor the control performance was given.
Keywords:measured disturbance  predictive control  performance monitoring  subspace identification
