In graduate class, education on shortening the lead-time in designing and developing products by various computer-aided systems in a network and applying virtual engineering was carried out. To accomplish such a purpose, network based education about engineering design was applied. Some laboratories consisting of various computer-aided systems were constructed and connected by a network. A samp...

plex project. But it has absolutely nothing to say about the stakeholder value of the system the project is developing. It serves a purpose, but needs to be incorporated into feedback control systems that focus on the real stakeholder value being earned. The value-based software engineering agenda, described in the “Accounting for Value in Software Engineering” sidebar, seeks to integrate value...

Black box models of technical systems are purely descriptive. They do not explain why a system works the way it does. Thus, black box models are insufficient for some problems. But there are numerous applications, for example, in control engineering, for which a black box model is absolutely sufficient. In this article, we describe a general stochastic framework with which such models can be bu...

The number of control loops used in industry is growing continuously and there are problems in keeping them working at a satisfactory level. One reason for the poor performance is the lack of maintenance of control loops. Economical benefits can result from the better maintenance of control loops. In this paper the economic aspects of control loop performance measures are discussed. A strategy ...

In this paper modelling and identification of a laboratory helicopter with the final aim to design a control system is presented. The CE 150 made by Humusoft is a laboratory helicopter designed for studying system dynamics and control engineering principles. First, the helicopter set-up is depicted. Next, theoretical and empyric modelling is systematically described. Identification of the neces...

Sometimes it is inconvenient or expensive to open the loop of a system to insert lag controllers—for instance, when this system is an open-loop system. A new controller structure where the loop is not opened, and that allows the design of lag controllers as in the case where one can open the loop, is presented. This result can be used by educators in undergraduate courses that deal with classic...

The paper treats MATLAB and SIMULINK courseware for education of the first two subjects in control engineering curriculum. The courses are based on simple SISO control using classical controllers, including simple nonlinear elements. Description of basic functions and programs and several examples of their use comprise the main part of the paper. The software is freely available on the Czech Te...
