Noise reduction in ECG signals for bio-telemetry
This document summarizes research on reducing noise in electrocardiogram (ECG) signals for biotelemetry applications. It describes implementing least mean square (LMS) and recursive least squares (RLS) adaptive filtering algorithms on ECG signals to reduce power line interference at 50Hz and additive white Gaussian noise. The ECG signals were processed from a public database and the algorithms were evaluated based on signal and noise power measurements and mean square error. Peak detection was also performed on the processed ECG signals and compared to the original signals without noise. Simulation results showed that both LMS and RLS algorithms could effectively reduce noise in ECG signals.
Noise reduction in ECG Signals for Bio-telemetryb
In Biotelemetry, Biomedical signal such as ECG is extremely important in the diagnosis of patients in remote location and is recorded commonly with noise. Considered attention is required for analysis of ECG signal to find the patho-physiology and status of patient. In this paper, LMS and RLS algorithm are implemented on adaptive FIR filter for reducing power line interference (50Hz) and (AWGN) noise on ECG signals .The ECG signals are randomly chosen from MIT_BIH data base and de-noising using algorithms. The peaks and heart rate of the ECG signal are estimated. The measurements are taken in terms of Signal Power, Noise Power and Mean Square Error.

This paper targets to demonstrate the importance of the choice of the
algorithm references detection to be applied with a double fuzzy PI corrector
(DFPI) for the control and the regulation of a shunt active power filter
(SAPF) DC bus voltage. In a previous work, the synchronous reference
frame (SRF) algorithm was applied and gave satisfactory results. In the
present paper, the SRF is compared to the positive sequence of the
fundamental of the source voltage algorithm (PSF) which offered better
results regarding the power quality of the considered main utility feeding a
variable DC RL load throughout a diode bridge. The results were carried out
using computer simulation performed under MATLAB/Simulink
environment. To make the obtained results more convenient, a comparison
between the couples (SRF, PI), (PSF, PI), (SRF, DFPI), (PSF, DFPI) is added
to prove the effectiveness of the couple (PSF, DFPI) in satisfying the
compromise between a good regulation of the SAPF DC bus voltage and a
good quality of filtering resulting in an improved quality of power.
PID controller using rapid control prototyping techniques
To analyze the performance of the PID controller in a buck type converter implemented in real time. We begin by designing a continuous controller using the analytical method for calculating PIDs. Pulse width modulation is then used and bifurcation diagrams analyzed to reveal some problems of switching and sampling time. The model converter is then implemented with a PID controller in dSPACE. The experimental results provide detailed requirements of sampling frequency and switching speed, and show the performance of the PID controller. Converters are used in power generation solar systems and conmuted power sources for feed telecommunication devices, smart grids, and other applications.

This paper presents a robust control strategy for a grid connected photovoltaic system with a boost converter by using an integral Backstepping method based on a nonlinear state model, which guarantees the Lyapunov stability of the global system. The system has tracked precisely the maximum power point, with a very fast response and the unit power factor has been observed under different atmospheric conditions. Moreover, the best advantage of the controller is that it’s a good corrector of the grid perturbation and system parameter disturbance. The simulation result has demonstrated the performance of this strategy.

This document compares the performance of a five-level photovoltaic inverter using two different maximum power point tracking (MPPT) algorithms: perturb and observe and incremental conductance. The five-level inverter topology uses a novel pulse width modulation control scheme. Simulation results show that using the incremental conductance MPPT algorithm reduces the total harmonic distortion from 39% to 28% and improves the power factor compared to using the perturb and observe MPPT method under changing atmospheric conditions. The incremental conductance MPPT algorithm can also track maximum power points more rapidly than the perturb and observe method.

This document summarizes a research paper that proposes using shunt hybrid active power filters to reduce current harmonics produced by a 3-phase uncontrolled bridge rectifier load. The rectifier produces balanced current harmonics of order 6n±1. Two shunt hybrid active filters are connected at the point of common coupling. One filter is tuned for the 5th and 7th harmonics, while the other filter reduces all other harmonics up to the 29th. Each hybrid filter combines a passive filter with an active inverter to inject "positive inductance" and dynamically tune the passive filter frequencies. Simulation results in MATLAB/Simulink show this method can effectively reduce current harmonics under harmonically balanced conditions.

1. The paper proposes using a shunt active power filter (SAPF) with a phase locked loop (PLL) control circuit to mitigate source current harmonics from a distorted voltage source supplying an unbalanced and nonlinear load.
2. Simulation results show that without the PLL, the SAPF has little effect on reducing harmonics. But with the PLL extracting the fundamental voltage component, the SAPF is able to reduce the total harmonic distortion of the source current to within IEEE standards.
3. The PLL provides a pure sinusoidal reference signal to the SAPF control scheme, allowing it to compensate for harmonics effectively even with a distorted supply voltage, without needing an additional series active power filter.
