Hardware-in-the-Loop simulation applied to roadheader cutting head speed control system testing

Abstract

This paper presents a description of the test stand and results of the Hardware-in-the- -Loop simulation for the angular speed control system of roadheader cutting heads. The system has been implemented in the LabView package using National Instruments cRIO and cDAQ devices. The system uses a discrete PI controller implemented with a cRIO FPGA module. Some results of simulation tests undernormal operating conditions and in emergency conditions have been presented.
