基于冲击负荷扰动的自校正控制器设计

Design of A Self-turning Algorithm for Overcome the Disturbance of Impulse Load

本文针对攀钢自备电厂１００ＭＷ单元机组过热蒸汽温度系统承受冲击负荷的问题，提出了一种实用的自校正算法。先利用广义内模概念，导出最优滑动平均滤波器，然后设计出改进的广义预测自校正控制器。理论分析和数字仿真表明，所设计的自校正控制器能抑制冲击负荷干扰，具有较强的鲁棒性。

This paper presents a useful self turning algorithm for overcoming the disturbance of impulse load.Indentification the system modle uses the advance least squares method besed on CARMA.With the optimal moving average filter for overcoming impulse load,A advantage Generalized Predictive Control(GPC)based on the retrocession modle of h(t)is designed.From aspects of theoritical analysis and digital simulation,the self-turning controller designed features strong robustnest on rejecting impulse load.
