In the paper it is investigated, under which conditions a time variable state transformation can be used to change a periodic autonomous system realization into a form with constant real coefficients. Conditions for the transformation to be periodic

Grinding systems are often modelled by multivariable impulse response or weighting function matrices. These kind of models are very suitable for design of model predictive controllers. Two predictive control algorithms have been developed and tested

The time for material to pass through a plug flow vessel is modelled by a delay function. If the flow rate is time-variable, the varying delay is difficult to calculate analytically even for general test functions of the flow rate. In this paper, the

The paper presents a new method for modelling of complex processes containing unkown qualitative varlables. The method is based on grouping the input-output-palrs of the model into a finite nunlber of clusters each representing different values of un

A physical continuous flow process of unknown structure is identified under constant and variable flow rates by testing it in a well instrumented laboratory enviroment. The pH numbers of its input and output streams are measured continuously, convert

The pilot manufacturing cell processes objects which belong to a product family. They arrive at the cell on a conveyor on which they lie in random order and in random positions and orientations. They are picked up and handled, drilled, milled and mea

Dynamic model of the rotary grinding mill with variable material flow is a superposition of the kinetic grinding process and the flow pattern characterized by the residence time distribution. A dimensionless residence variable is introduced by integr

Models of continuous flow vessels with variable volume and flow are studied and methods are developed for their recursive identification. New, composite variables have been introduced recently and it has been proven that many time-variable flow syste
