Buildings served by multiple rooftop units (RTUs) are widely prevalent in retail and food industries. Till date, most of such buildings utilize plain feedback or heuristic strategies to determine the RTU operations. We present a switched dynamic programming based approach for scheduling rooftop unit operations in an optimal manner. Using a mid-size restaurant served by multiple RTUs as an example,...
The paper presents an evaluation procedure for a few promising Model Predictive Control (MPC) based approaches in supervisory control of building heating, ventilation and air-conditioning (HVAC) systems. A case study is established and control trajectories are generated using the proposed solvers. The resulting trajectories are evaluated in terms of benchmark metrics taking energy costs and occupant...
A generalized notion of the input-to-state ℒ2-gains of discrete-time switched linear systems is proposed in this paper. Such gains are then characterized using the radii of convergence of a family of suitably defined functions called the generating functions. Properties of the generating functions are studied and their numerical computation algorithms are developed. Some numerical examples are presented.
In this paper, we propose a new method to evaluate air traffic complexity in 3‐D airspace through a probabilistic measure of the airspace occupancy. The key novelty of the approach is that uncertainty in the future aircraft positions is explicitly accounted for when evaluating complexity. Analytic—though approximate—expressions of the complexity measure are derived.
Prospective applications for the...
