Utilizing construction quality standards for almost perfect building projects ensures future marketability of projects, customer satisfaction and maximization of asset value. This paper describes a novel robot system to autonomously assess the post-construction quality of buildings which is currently done manually by using human inspectors. However, manual inspection always has the disadvantages,...
This paper describes a dynamic modeling and control of a multizone building where the thermal exchange, the coupling between the areas and the human occupation energy are taken into account. The thermal regulation in the building is ensured by a HVAC (Heating, Ventilation and Air Conditioning) system in which many parameters are involved. The HVAC systems are the main equipment for human life, but...
Heat integrated distillation columns (HIDiC) can save around 50% of energy consumption compared to conventional distillation columns. To reach this amount of energy saving, the HIDiC should be properly controlled. The high thermally coupled nature of HIDiC leads to high loop interactions making HIDiC difficult to control. In order to improve control performance, inferential active disturbance rejection...
Reducing building life cycle cost has been an important issue where minimizing the operational energy use and the maintenance cost are of primary concerns. This paper presents a new approach to model predictive control, where the above objectives can be addressed directly for the energy use and at least indirectly for the maintenance cost. In the predictive control formulation, we explicitly consider...
This paper presents a model-based approach to fault-adaptive control for damper lock-in place failures in variable-air-volume (VAV) boxes in building heating, ventilation and air-conditioning systems. The fault-adaptive controller integrates a dedicated bank of unknown input residual generators for fault detection/isolation followed by suitably designed fault estimators and a model predictive controller...
