Review on PID Controller with Intelligent System

This paper exhibited a survey investigation of tuning of Proportional Integral Derivative (PID) Controller for speed control of CSTR PLANT utilizing delicate processing strategies. CSTR PLANT engine is generally utilized as a part of businesses regardless of the possibility that its support cost is higher than the enlistment engine. Speed control of CSTR PLANT is pulled in extensive research and a few techniques are advanced. The PID controller is the generally utilized remunerating controller which is utilized as a part of nonlinear frameworks. This controller is broadly utilized as a part of a wide range of zones like aerospace, process control, manufacturing, automation and so forth. The tuning of PID parameter is extremely troublesome. There are different delicate processing systems which are utilized for tuning of PID controller to control the speed control of CSTR PLANT. Tuning of PID parameters is essential on the grounds that these parameters greatly affect the dependability and execution of the control framework

Recovery of RF Signal from Modulated Optical Signal

In previous proposed system, Radio frequency signal was transmitted through RF system. But the system had some disadvantages like non coherence and system was not efficient. This was overcome by using RF to optical domain converter. But that signal has to be recovered by converting the optical signal back to RF signal. This can be done by this system i.e. Optical to RF converter which is having photo detector, TIA and LNA. Here the modulated optical signal is detected by using photo detector, which detect the light signal and convert it to current signal. This current signal is converted to voltage signal and then required amplification is provided by using a LNA. Hence this system is a compact, and efficient system which is to provide a high speed optical to RF conversion.

Conversion of RF Signal to Optical Signal Using MZM

In previous proposed system, Radio frequency signal was transmitted through RF system. But the system had some disadvantages like non coherence and system was not efficient. Hence to overcome these drawbacks, RF over Fiber system is proposed. In the proposed system, RF signal is the message signal which is used to modulate the optical signal that has to be transmitted over the optical cable. Mach–Zhender Modulators (MZMs) are used to convert the RF signal to optical signal when the light cannot directly modulate for higher speed, the Lithium Niobate, Mach-Zhender Modulator (LN-MZM) is used, Continuous Wave Laser diode is used as the source and PIN diode is used as optical detector. To transmit the optical signal Polarization-Maintaining optical fiber (PMF or PM fiber) is used, this transmitted signal is detected at receiver by optical detector .Hence in RF over fiber system are small in size, these are flexible and is a very low loss technology using intensity modulation to transmit RF signal.

Speech Recognition in Noisy Environment-an Implementation on MATLAB

Speech is one of the ways to express ourselves naturally. So, speech can be used as a means to communicate with machines. In this work, using MATLAB as a platform isolated word recognizer is achieved. Speech signals get distorted by many kinds of noises. Hence, it is necessary to reduce the noise contained in the speech signal. This is called speech enhancement. Speech enhancement aims at improving the intelligibility of the speech. Noise has been removed using Spectral Subtraction with Over Subtraction technique. The feature extraction is carried out using MFCC and feature matching is achieved using HMM.

Wavelet Analytical Study of Solar Wind Proton Density

The solar wind is plasma, i.e., an ionized gas that fills the solar system. It results from the supersonic expansion of the solar corona. The solar wind consists primarily of electrons and protons with a smattering of alpha particles and other ionic species at low abundance levels. The structure of the heliosphere is strongly affected by the protons produced by the photo-ionization of the interstellar neutral hydrogen and by the charge exchange of the hydrogen atoms. The wavelet is a new analytical tool for turbulent or chaotic data to the physics community. It allows detection and characterization of short-lived structures in turbulence. Proton density fluctuations are studied using discrete wavelet transforms.
