Abstract
The escalating global population and depletion of energy resources have
intensified the challenge of energy conservation, with buildings alone
responsible for 30% to 40% of total energy consumption. Lighting,
constituting up to 20% of global energy usage, necessitates innovative
strategies for conservation. LED technology, renowned for its
efficiency, serves as a pivotal solution. Various control methods,
including proportional-derivative plus integral (PD+I) control, have
been explored to enhance energy savings while ensuring visual comfort.
Mathematical models, both linear and nonlinear, are employed for lamp
characterization and control scheme design. Simulation results
demonstrate the effectiveness of the proposed PD+I control in achieving
energy efficiency across different scenarios.
