Identification and Predictive Control of a Multistage Evaporator
A recurrent neural network-based nonlinear model predictive control (NMPC) scheme in parallel with PI control loops is developed for a simulation model of an industrial-scale five-stage evaporator. Input-output data from system identification experiments are used in training the network using the Levenberg-Marquardt algorithm with automatic differentiation. The same optimization algorithm is us...
متن کاملControl Scheme of Multistage Flash Plants
In this paper, the principals of large-scale desalination plants have been briefly introduced. Based on this, the essential aspects of obtaining a mathematical model of an MSF plant were presented in Section 3. This step of defining the main system variables and decomposing the large-scale system into its main subsystems is most important, whether the model is used for simulation or model-based...
متن کاملA Multivariate Quality Control Procedure in Multistage Production Systems
In this paper a multivariate quality control procedure is offered in which several correlated stages are present in production systems and in each stage there are several correlated control variable. Using Hotelling's T2 statistic, first, each stage is tested for being out of control. Then out of control variables are selected using Murphy's method. The remainder of the research involves evalua...
متن کاملData Representation for Flash Memories
In this chapter, we introduce theories on data representation for flash memories. Flash memories are a milestone in the development of the data storage technology. The applications of flash memories have expanded widely in recent years, and flash memories have become the dominating member in the family of non-volatile memories. Compared to magnetic recording and optical recording, flash memorie...
متن کاملSome Basic Observations on Heat Transfer and Evaporation in the Horizontal Flash Evaporator
This paper decribes a study of the heat, mass and momentum transp associated with vapor release in a horizontal stage of a flash evaporat A scaled-down, well-controlled flash evaporator, which also allows gc visual observation, has been designed, constructed and used in the expl ments. In particular, temperature profiles in the stage have been measured an accuracy of ±O.02°C and better. It has ...
