Economic MPC of Nonlinear Systems with Non-Monotonic Lyapunov Functions and Its Application to HVAC Control
This paper proposes a Lyapunov-based economic MPC scheme for nonlinear sytems
with non-monotonic Lyapunov functions. Relaxed Lyapunov-based constraints are
used in the MPC formulation to improve the economic performance. These
constraints will enforce a Lyapunov decrease after every few steps. Recursive
feasibility and asymptotical convergence to the steady state can be achieved
using Lyapunov-like stability analysis. The proposed economic MPC can be
applied to minimize energy consumption in HVAC control of commercial buildings.
The Lyapunov-based constraints in the online MPC problem enable the tracking of
the desired set-point temperature. The performance is demonstrated by a virtual
building composed of two adjacent zones
Mobility Study for Named Data Networking in Wireless Access Networks
Information centric networking (ICN) proposes to redesign the Internet by
replacing its host-centric design with information-centric design.
Communication among entities is established at the naming level, with the
receiver side (referred to as the Consumer) acting as the driving force behind
content delivery, by interacting with the network through Interest message
transmissions. One of the proposed advantages for ICN is its support for
mobility, by de-coupling applications from transport semantics. However, so
far, little research has been conducted to understand the interaction between
ICN and mobility of consuming and producing applications, in protocols purely
based on information-centric principles, particularly in the case of NDN. In
this paper, we present our findings on the mobility-based performance of Named
Data Networking (NDN) in wireless access networks. Through simulations, we show
that the current NDN architecture is not efficient in handling mobility and
architectural enhancements needs to be done to fully support mobility of
Consumers and Producers.Comment: to appear in IEEE ICC 201
