带有时变噪声系统内的不可测干扰的估计

ESTIMATION OF UNMEASURABLE DISTURBANCE OF IN A SYSTEM WITH TIME-VARYING NOISE

本文建立了带有时变噪声系统内的不可测干扰的通用模型。利用带有未知时变噪声的自适应Kalman滤波方法,对催化裂化装置中的不可测干扰进行了估计,结果表明,本方法具有较高的跟踪速度和精度。

In this paper a general model of unmeasurable disturbance ispresented. By using adaptive Kalraan filtering with unknown time-varying noise, the estimation of unmeasurable distxrbance can be made. Its application to fluidized catalytic cracking unit is shown.
