Energy Saving in a Copper Smelter by means of Model Predictive Control
Abstract
This chapter presents an application of advanced control techniques on a copper smelter. The main objective of the control strategy is to keep the gas-circuit pressure at its desired value while achieving energy saving. Another objective of the control strategy is to reduce the risk of emissions. This chapter describes the design and implementation of the gas-circuit control.
The design phase includes an identification procedure. This is a multivariable process where a thorough analysis is needed for input-output matching. The identification phase included the determination of the best input-output pairing.
The control strategy has been devised taking into account not only system performance but also implementation issues. The designed controller runs on a distributed control system (DCS) using the available single-loop blocks and is able to perform a predictive control strategy with feedforward action using existing PID and lead-lag blocks.
