The study of max-type difference equations attracted recently a considerable attention, see, for example, 1–27 , and the references listed therein. This type of difference equations stems from, for example, certain models in automatic control theory see 28 . In the beginning of the study of these equations experts have been focused on the investigation of the behavior of some particular cases o...

The concept of control has been around throughout history, but until recently it has predominantly involved human interaction (e.g. steering / maintaining speed of a horse, car or bike), in particular it wasn’t until around 1920 when there was a rapid development in automatic control devices [1, p.vii]. Control theory uses mathematical notation to analyse a problem; it does not particularly car...

This work summarizes some results about static state feedback linearization for time-varying systems. Three different necessary and sufficient conditions are stated in this paper. The first condition is the one by [Sluis, W. M. (1993). A necessary condition for dynamic feedback linearization. Systems & Control Letters, 21, 277–283]. The second and the third are the generalizations of known resu...

In this paper, a remote laboratory of automatic control is presented. The main target of this laboratory is to allow students to easily interact with a set of physical processes through the Internet. The student will be able to run experiments, change control parameters, and analyze the results remotely. The automatic control telelab (ACT) allows the user to design his/her own controller by mea...
