This paper proposed a saturated adaptive barrier sliding mode control (SABSMC) for disturbed systems with parameter uncertainty, external disturbance, and input saturation. One distinctive feature of the method is that even under influence saturation, it able to drive system trajectory into prespecified neighbourhood surface, independent upper limit lumped disturbance. Moreover, attributing des...

Nonlinearities due to photodetector saturation limit the maximum dynamic range achievable in short fiber optic links. We demonstrate an adaptive method for photodetector linearization using a monolithic CMOS polynomial generator. Improvements of 16 dB and 5.1 dB are achieved in the 2 and 3 order limited dynamic ranges, respectively.

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

This paper is concerned with the anti-saturation control problem of a permanent magnet synchronous wind power system. By virtue adaptive sliding mode method and port-controlled Hamiltonian (PCH) method, new coordination controller designed, which removes input saturation effects compensates uncertainties system model parameters. The takes exponential function parameters as function. adjusting f...

An adaptive output feedback control scheme is p r e sented for output tracking of a class of continuoustime nonlinear plants. An FU3F neural network is used to adaptively compensate for the plant nonlinearities. The network weights are adapted using a Lyapunovbased design. The method uses parameter projection, control saturation, and a high-gain observer to achieve semi-global uniform ultimate ...

We consider the adaptive lowest-order boundary element method (ABEM) based on isotropic mesh-refinement for the weakly-singular integral equation for the 3D Laplacian. The proposed scheme resolves both, possible singularities of the solution as well as of the given data. The implementation thus only deals with discrete integral operators, i.e. matrices. We prove that the usual adaptive mesh-ref...

In wireless distributed sensor networks, one open problem is how to guarantee the reliable relay selection based on the quality of services diversity. To address this problem, we focus on the reliable adaptive relay selection approach and adaptive QoS supported algorithm, based on which we present a Markov chain model, in consideration of different packet states and error control algorithm assi...

In this work, bromelain is recovered from triturated pineapple stem and rind (usually kitchen waste) through the precipitation process with alcohol at low temperature. The temperature control is crucial to avoid the irreversible protein denaturation and consequently improving the precipitation yield. The process is carried out in a fed-batch system, so that its dynamic nature poses challenging ...

This paper proposes a simple and efficient approach for reducing Motion Artifact (MA) in corrupted PPG (Photo Plethysmo Graphic) Signals based on AS-LMS Adaptive Filter. The performance of pulse oximeters is highly influenced by motion artifact in PPG signals. To generate the noise reference signal for an adaptive filtering process, instead of using any additional hardware such as accelerometer...

We introduce a new method of adaptive routing on k-ary ncubes that we refer to as Globally Adaptive Load-balance (GAL). Unlike previous adaptive routing algorithms that make routing decisions based on local information (typically channel queue depth), GAL senses congestion globally using segmented injection queues to decide the directions to route in each dimension. It further load balances the...
