Synthesizing Stability Regions for Systems with Saturating Actuators
Synthesizing Stability Regions Systems Saturating Actuators
2015/7/10
This paper presents a method of synthesizing controllers for systems with input saturation that guarantees state space regions of attraction. While the computation of stability regions and the corresp...
Optimizing Dominant Time Constant in RC Circuits
Optimizing Dominant Time Constant RC Circuits
2015/7/10
We propose to use the dominant time constant of a resistor-capacitor (RC) circuit as a measure of the signal propagation delay through the circuit. We show that the dominant time constant is a quasico...

Connections Between Semi-Infinite Semidefinite Programming
2015/7/10
Some interesting semi-infinite optimization problems can be reduced to semidefinite optimization problems, and hence solved efficiently using recent interior-point methods. In this paper we discuss se...

2015/7/10
For wireless ad hoc networks with multihop transmissions and Rayleigh fading, this paper maximizes the overall system throughput subject to QoS constraints on power, probability of outage, and data ra...
Simultaneous Routing and Resource Allocation via Dual Decomposition
Communication systems networks optimization methods resource allocation routing
2015/7/10
In wireless data networks the optimal routing of data depends on the link capacities which, in turn, are determined by the allocation of communications resources (such as powers and bandwidths) to the...

2015/7/10
The optimal routing of data in a wireless network depends on the link capacities, which, in turn, are determined by the allocation of transmit powers across the network. Thus, the optimal network perf...
