Advanced control software framework for process control applications

Abstract

Industries are now moving towards PC-based control from PLC (Programmable Logic Control) based control as the PC (personal computer) is easily available and capable of implementing various control strategies to improve productivity. Advances in both hardware and software technology are expediting this move. Absence of a user friendly, cost effective and easy to apply advanced control strategy based software is the motivation for this work. In this paper we reviewed issues of software application in process control systems. We present the development of an advance process control software tool and its application on a pH neutralization plant. Neural network model based DIC (Direct Inverse Control) strategy is implemented to control the process. The application and results shows the viability and robustness of the advanced control software and its superiority over the conventional PID (proportional integral derivative) controller.

Edge Computing in an IoT Base Station System: Reprogramming and Real‐Time Tasks

“…PLCs are common in industrial fields [25][26][27][28][29] because they are highly reliable and easy to program [30]. Moreover, they were standardized as early as the 1990s under IEC61131-3 [3].…”

“…PLCs can be divided into two rough groups according to their hardware architecture: embedded PLCs (ePLCs) and PC-based PLCs. PC-based PLCs offer more user-oriented tools [30], while ePLCs are cheaper and use less power. Given that user-oriented tools are not the focal point of BSIS, ePLCs are a more suitable choice.…”
