Performance Comparison of Two Electronic Controllers on an ARM Platform

Abstract:

Nowadays, the advances in technology and the development of new processes have driven the engineering areas to implement new control strategies to optimize the use of resources, thus guaranteeing the quality of the final product. This document presents a comparative study of two electronic controllers; a modern incremental Reference Signal Tracking (RST) control and a conventional Discrete Proportional Integral and Derivative (PID) control, aimed at a temperature process belonging to a Control Plant Trainer (CPT) developed on an STM32F4 platform with Advanced RISC Machine (ARM) technology. In order to know the efficiency of the modern Incremental RST control, the operation comparison is made against a Discrete PID control under the same working conditions. The behavior of Incremental RST control against conventional PID control is statistically analyzed using data obtained both in simulation and in real time, through Matlab specialized Simulink software, together with the Waijung library for data delivery and acquisition.
