Development of a model predictive controller for a milling

Since model predictive control can address most of these difficulties quite well, it was decided to design and test a model predictive controller for a milling circuit. Model predictive control Model predictive control (MPC) uses a dynamic model of the plant to predict the future actions of the manipulated variables on the plant output.

The Non-Linear adaptation of a Multi-Variable Predictive

The mining industry has recently been looking at MPC technologies because economic pressures dictate that maximum value be extracted from their process equipment. The application of MPC to milling circuits poses a number of technical challenges. These challenges arise from the discrete events, non-linearities and time

Most of these circuits are controlled only by PID controllers. With the HIL platform, it was possible to simulate actuators and sensors, in addition to allowing the development of a supervisory model predictive controller (MPC) to generate remote setpoints (SP) for the PID controllers using the industrial control blocks built into the DCS.
