This report presents measuring and identifications of the process in papermachine PM4 Gruvöns Bruk, Grums.
Our intention was, except the measuring itself, to improve, if possible, the system model now used for process control with an IBM 1710 system.
The measurings were accomplished during the last two weeks of February 1969, and included six series of about 2000 samples each using a sam
In this work we have discussed some alternatives to digitize the signals from different measurement devices. As a result of the work we have got a prototype for a digital interface as well as systems for digital representation of signals in temperature and pressure systems.
The report is divided into two parts, temperature and pressure measurements.
In this section of temperature measurem
In this report multi-input systems are treated by considering the input vector consist of two elements, its magnitude which is a scalar, and a unit vector representing the direction of the control vector (i.e. the ratio between the control signals) in the linear space formed by the control vectors (III:1).
A formalism for representing multi-variable systems in matrix-form, where the magni
