ℓε-Regularized Economic Model Predictive Control for Thermal Comfort in Multizone Buildings

Abstract

This paper presents a new thermal regulation technique for multizone buildings, possibly equipped with discontinuously (on/off) operating HVAC actuators, based on regularized economic model predictive control (REMPC). In the presence of actuators operating on an on/off basis, it often happens that the control scenario resulting from such a strategy is very “aggressive” towards these same actuators due to the many on/off cycles. This phenomenon can lead to premature wear of the actuators most sensitive to these repeated state changes (especially heat pump compressors). In order to take into account the “aggressiveness” of a control scenario and to increase the lifetime of the actuators, an economic criterion with a regularization term based on the parsimony-promoting property of the ℓε-norm (ε small) is used. This term is sufficiently generic to allow the regularization of the optimal control law by taking into account discontinuous control inputs (on/off), reducing the number of actuators used at any given time or avoiding inappropriate control scenarios (alternating use of heat pump in heating/cooling modes,...). To solve the minimization problem of the non-convex ℓε-regularized economic criterion, we use an iterative algorithm recently derived in (Gabsi et al., 2018b). The effectiveness of the proposed control strategy is illustrated on the “Eco-Safe” platform at CRAN Nancy, France.
