**5.1. Utilization of virtual dynamical models**

Except of the presented GUI screens of virtual models a series of tens other models from fields of electrical engineering and mechatronic systems was developed to suit institutional needs. They cover topics from Electrical Machines, Power Electronics, Electrical Actuators and Drives, Servodrives, Mechatronic Systems, Control Theory, and others. We have also developed some more complex GUIs, reported e.g. by (Ismeal & Fedák, 2012), calculating artificial intelligence algorithms - to design PID controllers using fuzzy logic and genetic algorithms with various objective functions to evaluate the best PID controller.

The developed GUIs serve as virtual models to clarify phenomena and enhance features of the systems during lectures, and to prepare students for laboratory work. In order students to get more skills and practical experiences prior entering lab their work consists of two phases:

*Design and simulation* – for a given system motor or drive a student has:


Verification and analysis – a student has:
