Model Predictive Control of Climatic Chamber with On-off Actuators
2014
Abstract This article presents modelling and control of a climatic chamber with on/off actuators. Controlled environmental variables in the chamber are temperature, relative humidity and illumination. The system is first decoupled by nonlinear transformation and a linear model is identified using subspace methods; further, a model predictive control strategy for processes with on/off actuators is presented. The controller incorporates set-point filtering to deliver smooth climate transitions. The control results from a real climatic chamber are attached.
