Description: 随着这些年计算机硬件水平的发展, 计算速度的提高, 源自序列蒙特卡罗方法的蒙特卡罗粒子滤波方法的应用研究又重新活跃起来。本文的这种蒙特卡罗粒子滤波算法是利用序列重要性采样的概念, 用一系列离散的带权重随机样本近似相
应的概率密度函数。由于粒子滤波方法没有像广义卡尔曼滤波方法那样对非线性系统做线性化的近似, 所以在非线性状态估计方面比广义卡尔曼滤波更有优势。在很多方面的应用已经逐渐有替代广义卡尔曼滤波的趋势。-With the years the level of computer hardware development, the speed of calculation, derived from the sequence of the Monte Carlo method, Monte Carlo particle filter method applied research has once again become active again. In this paper, this kind of Monte Carlo particle filter is to use the concept of sequence of the importance of sampling, using a series of discrete random sample with weights similar to the corresponding probability density function. Since the particle filtering method is not as broad as Kalman filtering method for nonlinear system to do linear approximation, nonlinear state estimation in the generalized Kalman filter than an advantage. Applications in many areas has been gradually generalized Kalman filter has an alternative trend. Platform: |

Description: This paper deals with digital control of a series
active filter integrated with a diode rectifier where the series
active fdter is controlled to function as a current source.
A predictive current regulator is considered for the series ac-
tive filter to achieve good ripple characteristics and predictable
switching losses. The operating conditions, and the effect
thereof on the current regulator are considered and oversam-
pling and prediction of the load voltage is suggested to improve
the active filtering performance without increasing the switching

Description: A control algorithm for a three-phase hybrid power filter is proposed. It is constituted by a series active filter and a passive
filter connected in parallel with the load. The control strategy is based on the vectorial theory dual formulation of instantaneous
reactive power, so that the voltage waveform injected by the active
filter is able to compensate the reactive power and the load current
harmonics and to balance asymmetrical loads. The proposed algorithm also improves the behavior of the passive filter. Simulationshave been carried out on the MATLAB-Simulink platformwith different loads and with variation in the source impedance.This analysis allowed an experimental prototype to be developed.
Experimental and simulation results are presented. Platform: |

Description: Elimination of Voltage Harmonic Produced by SSSC by Using Series Active Power Filter.
This paper describes the development of a series active power filter with hysteresis control, which allows
harmonics and zero-sequence voltage compensation. Here, the series active filter play an important role in
harmonic voltage cancellation produced by Static Synchronous Series Compensator SSSC when is
connected in the electrical network. The active filter controller is based on the instantaneous power theory
(p-q theory) and was simulated by using MATLAB SIMULINK. The p-q theory is introduced followed
by the presentation of some active power filters topologies. Then a brief description of the implemented solution is made, using references of software tools used for simulation and system development. The obtained results are also presented, showing the good performance of the developed active filter. Platform: |
