Digital Simulation and implementation of a Power Factor Correction (PFC) half bridge converter based adjustable speed voltage controlled VSI fed PMBLDC motor is presented in this paper. A single-phase AC-DC converter topology based on the half bridge converter is employed for PFC which ensures near unity power factor over wide speed range. The proposed speed control scheme has the concept of DC...

The use of rapid prototyping tools such as MATLABSimulink and Xilinx System Generator becomes increasingly important because of time-to-market constraints. This paper presents a methodology for implementing real-time DSP applications on a reconfigurable logic platform using Xilinx System Generator (XSG) for Matlab. The methodology aims to improve the design verfication efficiency for such compl...

This paper deals with two popular and powerful methods in noise and harmonic detection field of digital signal processing. The first one is the Windowing technique and the other one is wavelet transform. The proposed method uses these methods in the traditional synchronous fundamental dqframe algorithm. In other words, a windowing-wavelet based method is formed as a low pass filter. The Hamming...

In this paper Adaptive filter is designed and simulated using different algorithms for noise reduction in different signals. The developed filter has been analyzed using Least Mean Square (LMS), Normalized Least Mean Square (NLMS) and Recursive Least Squares (RLS) algorithms for sinusoidal, chirp and saw-tooth signals. The performance of developed filter has been compared interms of Rate of Con...

In this paper the problem of detecting and isolating faults on the actuators of a small commercial aircraft using online approximators is dealt with. In particular the capabilities of radial basis neural networks to approximate faults on the engines and elevators of an AP-68 Vulcanair commercial aircraft are investigated also in the presence of model uncertainties and external disturbances. The...

The Matrix converter is a forced commutated Cyclo-converter with an array of controlled semi conductor switches that connects directly the three phase source to the three phase load. The matrix converter is a direct AC-AC Converter. It has no limit on output frequency due to the fact that it uses semiconductor switches with controlled turn-off capability. The simultaneous commutation of control...

In this study, we took advantage of the emergence accurate biomechanical human hand models to develop a system in which interaction between arm and rehabilitation robot while performing planar trajectory tracking task can be simulated. Seven were based on 11-degree-of-freedom Dynamic Arm Simulation model implemented OpenSim. The was developed MatlabSimulink achieved using OpenSim API. tested by...

This paper discusses the control of flexible microgrids, consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this conve...

The main focus of this article is to investigate the effects of Adaptive control on the switching frequency and Total Harmonic Distortion of a modified, minimally switched hysteresis controlled shunt active power filter. Reference current generation was done using Instantaneous real and reactive power algorithm. Pulses to the minimally switched grid interactive inverter in which only two switch...
