Period Estimation of Medium Plate Double-Stands Serial Production Line with Parameters Perturbation

为了解决一类中厚板双机架串行生产线参数摄动条件下周期值估计的问题,在建立该系统极大代数意义下的状态空间模型的基础上,采用一种系统参数摄动时周期值的估计方法,对实际系统的周期值进行了估计.研究结果表明,该方法与实际计算的周期值相比,计算量小,能够有效地估计出带有参数摄动的串行生产线的周期值的上界,并对串行生产线的轧制工艺提出了改进方法,防止串行生产线因参数摄动而发生阻塞,提高了串行生产线的安全性.

To estimate the period of medium perturbation, a computation method is presen pl te ate double-stands d to estimate the p its state-space model in max-algebra. The research result shows algorithm to compute the period, the proposed method can est period of serial production line under parameter perturbation with measure to improve rolling technology is proposed to prevent pro production line with parameter eriod of actual system based on that compared with the actual imate the upper bound of the lower computation. Also, the duction blocking caused by the parameters perturbation so as to increase the security of the serial production line.
