Comparison between fuzzy control and MPC algorithms implemented in low-cost embedded devices

This paper presents the design of two advanced control algorithms applying low-cost embedded boards. To obtain experimental results a flow plant design was used. For the first part of the work detailed in this paper, a fuzzy controller was designed and implemented in different embedded boards such as Arduino Uno, Raspberry Pi 3, BeagleBone Black and Udoo Neo Full. Next, an MPC was developed in the Raspberry Pi 3 board, being the only device that provides the necessary technical requirements for the design. Further, the signal conditioning before and after the controller integration with industrial equipment is described. To demonstrate the performance of each board used, and to acquire the data in real time two interfaces were created, for the first controller the interface was developed in LabVIEW software, and for the second one a GUIDE interface was developed in MATLAB software. The tests carried out validate these proposals, which despite the computational cost they require, they present high performance, robustness and good response, when tested in the flow system design. © Springer Nature Switzerland AG 2020.
