The Propagation Mode and Multiple Feedback Control of Multiple Parameters Generalized Uncertainty in Series System

The concept of multiple parameters generalized uncertainty(MPGU) is introduced in parameter uncertainty propagation problem for series system in the paper.A multiple parameters generalized uncertainty model for series system is proposed.This model shows some detail information not only about the variation in the process of parameter uncertainty propagation,but also significant influence formed by elements in the propagation matrix.The characteristic of propagation matrix and the dominant or collateral role of every subsystem in the series system are both illustrated in detail.In the end,a multiple feedback control model of MPGU in the series system is proposed.Furthermore,multi-class feedback control models referring to single subsystem,double subsystems and even multi-subsystem are acquired later.The model proposed in this paper demonstrates theoretically the output parameters uncertainty variation and its upper bound area norm when the modification of the propagation matrix is achieved,which can be regarded as a good support in engineering.
