Direct digital control scheme for controlling hybrid dynamic systems using ANN state estimator and inverse dynamics controller

An Estimator Based Inverse Dynamics Controller (EBIDC), which utilizes an Artificial Neural Network (ANN) based state estimation scheme for nonlinear autonomous hybrid systems which are subjected to state disturbances and measurement noises that are stochastic in nature, is proposed in this paper. A salient feature of the proposed scheme is that it offers better state estimates and hence a better control of non-measurable state variables with a nonlinear approach in correcting the a priori estimates by avoiding statistical linearization involved in existing approaches based on derivative free estimation methods. Simulation results guarantees significant reduction in Integral Square Error (ISE) and standard deviation (σ) of error, between the controlled variable and set point and control signal computation time when compared with best existing related work based on Unscented Kalman Filter (UKF) and Ensembeled Kalman Filter (EnKF).

Adjustable Spectral Characteristics to Design FIR Filter Using Two-Variable Window Function

This paper present a new dynamic window function having variable or adjustable spectral characteristics. A new dynamic window function proposed in this paper is a combination of hamming, Blackman-Harris, chebwin, and Kaiser Window function. Blackman-Harris, chebwin, and Kaiser Window functions have been used to compare with the suggested proposed window function i.e. a combination of hamming, Blackman-Harris, chebwin, and Kaiser Window function.

Improved Single Haze Removal using Weighted Filter and Gaussian-Laplacian

This paper exhibits a study about various image defogging techniques to eject the haze from the fog images caught in true world to recuperate a fast and enhanced nature of fog free images. In this paper, we propose a simple but effective the weighted median (WM) filter was first presented as an overview of the standard median filter, where a nonnegative integer weight is assigned to each position in the filter window image .Gaussian and laplacian pyramids are applying Gaussian and laplacian filter in an image in cascade order with different kernel sizes of gaussian and laplacian filter .The dark channel prior is a type of statistics of the haze-free outdoor images.

Butterfly Shaped Patch Antenna for 5G Application

Widely used patch in circular shape has been cut in two semicircular shapes and joined together, arc to arc to same feed in dipolar form, produces a butterfly shape. In this paper each semicircular shapes are remodeled as bi-circular shapes for enhancement of gain so that it can be operated at a frequency of 15GHz which is applicable for 5G communication. This antenna is placed on a substrate of FR4-epoxy material. The design of the shape is based on the minimum distance of the two extreme arcs of the two parts which becomes the wavelength of the required resonant frequency. This design is compatible with all antenna requirements including S11 plot from which the resonant frequency and return loss have been determined. The software used in HFSS, by which antenna parameters like antenna gain, directivity etc have been checked. The patch and the ground plane is of same material, copper.

Overview of the Conversion of Traditional Power Grid to Internet Energy

In the information society, no human activity stands still, including the electric power industry. As a result, there has been a shift from a traditional grid architecture to a new information and communication technology architecture. The object of the study of this article is a smart power supply system. The purpose of the study is to consider problems for implementing the concepts of "Smart Grid" and "Internet of energy." To do this, a brief overview was made of the traditional electricity supply system, as well as promising renewable energy sources and its promising directions. In order for several RSE to exist in the same power grid without any problems, it is necessary to use energy routers that are able to connect several power grids operating on different sources. The received system monitor by the power grid management systems (SCADA, distributed control system). There are also discussed the SCADA tasks and features. The above all leads to the implementation of two innovative concepts in the field of energy: Smart Grid and Internet energy.
