The control of power electronic converters is subjected to several challenges as measurement sensors drift, malfunction in harsh environments, non-ideal grid, and performance degradation due to the delay of discrete control systems. In this paper, a stationary frame resonant current controller for inverter-based distributed generation (IBDG) with sensor-less grid voltage operation is proposed. The...
Networked controlled systems comprise a team of dynamic systems which are linked together through a shared networked. From control systems perspective, the introduction of a shared networked brings its own challenges such as packet dropouts, time delays and clock synchronization. A popular application of networked controlled systems is to consider a team of collaborative mobile robots. Networked controlled...
Due to the large variety of renewable power sources, power electronics play an important role in energy conversion. Different power converter topologies are used to interface distributed power generation systems (DPGS) with the utility network. Introduction of power electronics for DPGS provide several advantages such as energy optimal operation by employing a control algorithm to extract the maximum...
Wireless sensor networks and, particularly wireless body area networks (WBANs) are the key building blocks of upcoming generation networks. Modern health care system is one of the most popular WBAN application and a hot area of research in subject to present work. In recent years, research has focused on channel modeling, energy conservation and design of efficient medium access control (MAC) schemes...
Currently, in high performance computer systems, processors are faster and have vastly increased in performance and computational power. It is important for system designers to get an early estimation of power dissipation to meet the challenging methodologies for power dissipation reduction and optimization. In addition to the current design methodologies, the designer might need to consider the factors...
A new approach for simultaneous estimation of parameters and the time delay of continuous time transfer function models using piecewise linear input excitations is presented. A sinusoidal input can be approximated as a piecewise linear signal. Approximation equation for sinusoids has been provided and estimation equation for first order transfer functions has been derived which can be generalized...
Voice over Internet protocol service (VoIP) is growing fast during the last few years. Unlike the usual best effort traffic, the voice traffic is delay and delay jitter sensitive. The current scheduling schemes meet the voice traffic delay constraint by assigning its packets with the highest priority. This behavior is acceptable as long as the volume of voice traffic is relatively very small in comparison...
