Semidefinite Programming Relaxations of Non-Convex Problems in Control and Combinatorial Optimization
Semidefinite Programming Relaxations Non-Convex Problems Control Combinatorial Optimization
2015/7/13
We point out some connections between applications of semidefinite programming in control and in combinatorial optimization. In both fields semidefinite programs arise as convex relaxations of NP-hard...
Quadratic Stabilization and Control of Piecewise-Linear Systems
Piecewise-linear systems quadratic stabilization linear matrix inequality (LMI)
2015/7/13
We consider analysis and controller synthesis of piecewise-linear systems. The method is based on constructing quadratic and piecewise-quadratic Lyapunov functions that prove stability and performance...
Control of Asynchronous Dynamical Systems with Rate Constraints on Events
Asynchronous dynamical systems Lyapunov theory linear matrix inequality (LMI) bilinear matrix inequality (BMI)
2015/7/10
In this paper we consider dynamical systems which are driven by events that occur asynchronously. It is assumed that the event rates are fixed, or at least they can be bounded on any time period of le...
Optimal Power Control in Interference Limited Fading Wireless Channels with Outage Probability Specifications
Fading channels personal communication networks power control radio communication
2015/7/10
We propose a new method of power control for interference limited wireless networks with Rayleigh fading of both the desired and interference signals. Our method explicitly takes into account the stat...
The field of control provides the principles and methods used to design physical and information systems that maintain desirable performance by sensing and automatically adapting to changes in the env...
DTMW: A New Congestion Control Scheme for Long-Range Dependent Traffic
New Congestion Control Scheme Long-Range Dependent Traffic
2015/7/8
Recent measurements based on long empirical traces have revealed that many important types of traffic (e.g., LAN, WAN and VBR video) possesses long range dependent (LRD) characteristics. Studies have ...
Optimal Power Control for CDMA Systems in the Wideband Limit
Optimal Power Control CDMA Systems Wideband Limit
2015/7/8
Traditional methods for solving multiuser control problems in CDMA systems do not scale well as the number of users in the system increases. To address this problem we develop a wideband limit approxi...
Distributed Power Control for Time-Varying Wireless Networks
Distributed Power Control Time-Varying Wireless Networks
2015/7/8
This paper presents new distributed power and admission control algorithms for ad-hoc wireless networks in random channel environments. Previous work in this area has focused on distributed control fo...
