In this paper, we present a design methodology for synchrophasor estimation systems based on a convex semi-infinite optimization approach. Concretely, we present a suitable objective function for the problem and show how different performance constraints can be formulated. The advantage of this over most methods is that it allows us to control precisely and completely the behavior of the system on...
FFT is a crucial and necessary design entity lor any current communication applications, especially for OFDM systems. As compared with conventional design approach, which can support only one-radix processing kernel of single-path delay feedback (SDF) FFT, we propose a reconfigurable processing kernel design for multiple-radix types of SDF FFT. In implementation, this kernel hardware engine is reconfigurable...
Automatic loudness control (ALC) for broadcasting service has been deployed to guarantee the loudness legislation. In this paper, we introduce the low delay automatic loudness control (LD-ALC) in order to reduce the service degradation from the additional algorithmic delay. Performance results have shown that the proposed ALC provides no audible difference with low algorithmic delay fulfilled with...
For making Mobile ad hoc network (MANET) more energy efficient swarm intelligence is used as a base and the clustered based approach as Bee-Ad Hoc-C which is an evolution from Bee-Ad-Hoc has been chosen as the best method in our previous work along with Stable Cluster Maintenance Scheme. In the proposed method parallel routing has been considered to improve the scalability of the system, reduce the...
In this paper, for secure routing optimization we are introducing dynamic trust management protocol in information centric network and delay tolerant network (DTN) environments. In the existing system, dynamic trust management for DTN is used to deal with the detection of the selfish, malicious misbehaving nodes and genuine loss nodes. To disrupt DTN operations, malicious nodes performing trust-related...
The mobile devices are becoming the important part in our everyday life. These are now one of the basic needs of our daily life. These devices are used to share the data of interest with one another. Data may be in the form of picture or video clip, news etc. But sometimes, data cannot reach to the user who is interested, because of delaying of messages. Sometimes nodes do not want to loose their...
In distributed OpenFlow controller networks, the network flow is managed by set of associated rules that are maintained by switches in their local Ternary Content Addressable Memory (TCAM) and rules are made by concerned controllers, which are local to domains. However, TACM is expensive and consumes high power. The switch inside the forwarding plane has limited TCAM space and is infeasible to maintain...
This work aims to minimize average delay for an urban signalized intersection under oversaturated condition using genetic algorithm (GA). Relieving urban traffic congestion is an urgent call for traffic engineering. The effectiveness of traffic signalization is one of the key solutions to reduce congestion, but regrettably the current traffic signal control system is not fully optimized for handling...
A novel stabilization problem for T-S polynomial fuzzy system with time-delay is investigated in this paper. Firstly, a polynomial fuzzy controller for T-S polynomial fuzzy system with time-delay is proposed. In addition, based on polynomial Lyapunov-Krasovskii function and the developed polynomial slack variable matrices, a novel stabilization condition for T-S polynomial fuzzy system with time-delay...
The robust H-infinity controller design is investigated in this paper for a class of nonlinear singular systems with state and transmission delays. The proposed controller is configured in multiple feedback loops. Based on the interval type-2 T-S fuzzy modelling and parallel distributed compensation techniques, a fuzzy multiple feedback-loop controller with memoryless state and delayed states is proposed...
The sense of agency (SoA) describes the feeling of being the author and in control of one's movements. It is closely linked to automated aspects of sensorimotor control and understood to depend on one's ability to monitor the details of one's movements. As such SoA has been argued to be a critical component of self-awareness in general and contribute to presence in virtual reality environments in...
This paper considers the sliding mode control (SMC) for a class of state delayed systems subject to persistent disturbances. First, a disturbance compensator is proposed to eliminate the influence from persistent disturbances, and the stability of control system is discussed. Then, the control problem is transformed into sliding mode control problem for state delayed system without expression of disturbances...
In the development of advanced driver-assist systems (ADAS) for lane-keeping, one important design objective is to appropriately share the steering control with the driver. Hence, the steering behavior of the driver must be well known beforehand. This paper adopts the well-known two-point visual driver model to characterize the steering behavior of the driver, and conducts a series of field tests...
Natural load-bearing structures, such as trees, have had to strive for survival in harsh environmental conditions. Over time, these structures have evolved, and are able now to optimize their shapes. Behind this optimization is a simple yet powerful rule called the axiom of uniform stress, which has successfully been applied to topology optimization in various engineering fields. Similar to physical...
Super-resolution theory aims to estimate the discrete components lying in a continuous space that constitute a sparse signal with optimal precision. This work investigates the potential of recent super-resolution techniques for spectral estimation in multi-rate sampling systems. It shows that, under the existence of a common supporting grid, and under a minimal separation constraint, the frequencies...
This paper demonstrates synthesis of a robust wide-area controller for damping inter-area power system oscillation. A wide-area damping controller is more effective in damping inter-area modes in power system as it takes remote signal as feedback in which inter-area oscillations strongly observable. However, with the involvement of remote signal time-delay is introduced in the feedback loop causing...
A two degrees of freedom controller is designed for multiple inputs multiple outputs system with multiple time delays. An H∞ norm of closed loop optimized decoupled smith control method is used to design feedback controller for disturbance rejection. The reference tracking controller is determined using H2 norm of model matching optimal control design method. The parameters of the two controllers...
The utilization of orthogonal variable spreading factor (OVSF) in CDMA networks limits the number of calls which can be handled due to their orthogonal nature. Therefore, a multi code assignment scheme is required which can utilize efficiently the scattered vacant code over the period of time. This paper describes a scheme which is the extension of FFSP scheme. The multi code flexible fixed set portioning...
For stabilizing power frequency in the grid, demand-supply balancing capability by manipulating the demand side, known as Demand Response (DR), is getting attention because of the continuous increase in renewable energy resources and deferrable loads such as electric vehicles in addition to the traditional adjustment function by supply side such as thermal plants. In the future smart grid, it is imperative...
Software-defined networking (SDN) has been proposed as a new networking paradigm which separates the control and data forwarding planes. The controllers deployed as centralized network control entities are crucial for meeting the performance and efficiency requirements of these systems. The placement of these network entities, switch assignment and their load-aware operation are challenging research...
