Development of a high speed monitoring system using opensource hardware and MATLAB

초록

In this paper, we deal with the development of a high speed monitoring system using opensource hardware and MATLAB/Simulink. We use the Arduino Due as opensource hardware. The proposed high speed monitoring system has four features. First, it does not affect the operation of the user application running on a micro-controller. The proposed system performs realtime monitoring using an algorithm that minimizes the computational load. Second, data channels can have different data types and update periods. Consequently, flexible data monitoring is possible. Third, the proposed system uses MATLAB/Simulink for monitoring. As a result, users can utilize all the powerful functions supported by MATLAB to process the monitored data. Finally, the algorithm of the proposed high speed monitoring system can be applied to any micro-controller with serial communication peripheral. Through experiments, we verify the performance of the developed monitoring system. It is shown that the data loss does not happen through the basic experiment. Through realtime monitoring experiment for the sensorless drive system of the BLDC motor, it is illustrated that the proposed system has its strength in high speed monitoring of data changing very fast such as current or back EMF signals. © ICROS 2019.
