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 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)
