Implementation of Model Predictive Control in Programmable Logic Controllers

In this article, we present an implementation of a low-memory footprint model predictive control (MPC)-based controller in programmable logic controllers (PLCs). Automatic code generation standardized IEC 61131-3 PLC programming languages is used to solve the MPC's optimization problem online. The designed for its application realistic industrial environment, including timing considerations and accounting possibility not being exclusively dedicated MPC controller. We describe architecture algorithm, show results memory with regard dimensions, hardware-in-the-loop multivariable chemical plant.
