The present article deals with a fault and delay tolerant multi-sensor control scheme. In particular, we consider a process affected by additive disturbance which is monitored by redundant sensors. The process is controlled by a digital controller which is connected with the sensors via shared network. It is assumed that sensors are subject to abrupt faults while the communication between the s...

To satisfy the requirement of real-time and accurate control system, a time-delay prediction system based on PSO-RBF neural network model is established to solve effect time delay system’s performance. Firstly, with predict output uncertainty delay. Secondly, an improved offline RBF networks proposed problem low accuracy in networks. that PSO algorithm prone fall into local optimality, nonlinea...

Transmission power control is essential in WCDMA in order to optimize the bandwidth utilization which is critical when variable data rates are used. One remaining problem is oscillations in the output powers due to round-trip delays in the power control loops together with the power up-down command device. The oscillations are naturally quantified using discrete-time describing functions, which...

We consider general discrete-time nonlinear systems (of arbitrary nonlinear growth) with time-varying input delays and design an explicit predictor feedback controller to compensate the input delay. Such results have been achieved in continuous time, but only under the restriction that the delay rate is bounded by unity, which ensures that the input signal flow does not get reversed, namely, th...

Recently, to achieve several services as multimedia service, the developing of the information and communication technologies is absolutely imperative. To achieve this demand, several techniques have proposed as orthogonal frequency division multiple access (OFDM), multiple-input multiple-output (MIMO), and cooperative communications. In this thesis, we focus on OFDM, MIMO and cooperative commu...

The main objective of this paper is to demonstrate the feasibility of Internet-based real-time control. A novel client/server-based architecture for Internet-based supervisory control with a Common Gateway Interface/Hyper Text Markup Language (CGI/HTML) interface is presented. A real-time operating environment was established for closed-loop control over Ethernet. We conceived of an autoregress...

There is increased interest in using microphone arrays in a variety of audio source separation and consequently speech processing applications. In particular, small arrays of two to four microphones are presently under focus in the research literature, especially with regard to real-time source separation and speech enhancement capability. In this paper we focus on a real-time implementation of...

A novel class of high-speed and tunable integrated photonic delay lines that compromise between loss and size is proposed. The devices consist of two cascaded apodized grating waveguides and with complementary (positively and negatively modulated) refractive index profiles for dispersion compensation. It is shown that the compact tunable delay lines are low-loss and offer long true-time delays ...

Contour control of a robot arm is an act of the end-effector tip being moved along a reference Cartesian path, with an assigned velocity. When torque saturation occurs, and lasts for some time, contour deteriorations result. In addition, system delay dynamics also causes contour deteriorations. In this paper, an offline trajectory generation algorithm is described, which achieves both optimum a...

Continuous-time ∆Σ modulators are able to operate at higher frequencies than their discrete-time counterparts. However, they suffer more severely from non-idealities such as clock jitter and excess loop delay. The effects of these two non-idealities are explained and a continuous-time to discrete-time conversion method is presented in order to aid in the analysis of these non-idealities. Two ci...
