The paper is focused on NI Compact-RIO configured as a controller for the active magnetic levitation used here as a benchmark for time-critical systems. Three real-time configurations: soft, soft with IRQ and hard FPGA are considered. The quality of the real-time control has been tested for each configuration.
—A current trend in learning programs, even at high-degree studies, is applying the concepts of " learning by projects ". In this context, the LEGO® MINDSTORMS® NXT modular robot appears as a simple, flexible and attractive educational platform to achieve the referred challenge in many domains of information technologies, especially in real-time control.… (More)
The paper describes the mechanism for involving students from multilingual, geographically separated institutions in a coordinated educational experience and presents the observations and evaluation of outcomes related to the collaborative project. The project was realized as a part of ILERT (International Learning Environment for Real-Time Software… (More)
The most popular configuration of the controlled laboratory testrigs is the personal computer (PC) equipped with the I/O board. The dedicated software components allows to conduct a wide range of user defined tasks. The typical configuration functionality can be customized by PC hardware components and their programmable reconfiguration. The next step in… (More)
This paper is an extension of previous work, where authors developed a nonlinear model and its linear approximation of bicycle (or single track vehicle generally) with controlled moment gyro (CMG) used for stability algorithm in vertical direction. Also, simple stability was proposed. This extension focuses on robustness of control.
A control numerical algorithm solving the timeoptimal problem for the reaction wheel pendulum system, fully effective in the open loop, is examined in the real-time system. There are two control tasks. The first is to transfer the pendulum from the lower to the upper equilibrium point. The second is to transfer the pendulum from the upper to the lower… (More)

The paper is an attempt to interest the reader how to control real-time mechatronic systems under the MS Windows operating system. The authors refer to solutions that combine a software part and a hardware using the FPGA technology, together forming a comprehensive platform for the control purposes in the real-time. The main emphasis is placed on the… (More)
