An experimental survey of feedback control methodologies for advanced lighting systems
Lighting constitutes a significant portion of building energy consumption. Various lighting control strategies exist that reduce the energy consumption by decreasing dimming level of the fixtures and also ensure the color quality of the achieved light. These strategies differ in their input parameters, control objectives, control algorithms, cost of installation, complexity of commissioning, availability of hardware, etc. Each of these control schemes has a unique set of factors that affect their performance in terms of energy savings as well as the achieved light quality. This paper presents an experimental survey of four state-of-the-art lighting control strategies, the formulation of their associated problems as well as their solution approaches, the experimental results obtained from their implementation in a standard testbed, and the factors affecting their performances.
