The Kalman filter has a wide range of applications, noise removal from corrupted speech being one of them. The filter performance is subject to the accurate tuning of its parameters, namely the process noise covariance, Q, and the measurement noise covariance, R. In this paper, the Kalman filter has been tuned to get a suitable value of Q by defining the robustness and sensitivity metrics, and then applied on noisy speech signals. The Kalman gain is another factor that greatly affects filter performance. The speech signal has been frame-wise decomposed into silent and voiced zones, and the Kalman gain has been adjusted according to this distinction to get best overall filter performance. Finally, the algorithm has been applied to clean a noise corrupted known signal from the NOIZEUS database. It is observed that significant noise removal has been achieved, both audibly and from the spectrograms of noisy and processed signals.

Online detection of onset of an earthquake and estimation of its epicenter is of paramount importance. Manual analysis is still the final resort to characterize a seismic event and various seismic phases (waves) associated with it. In this paper, an attempt has been made at multi-scale modeling of seismic array signal to automate detection of event onset, estimation of event location and automatic/ unsupervised report generation. The technique works in wavelet domain, exploiting the non-stationary property of seismic waves. After an event is detected, a section of the data around the P onset is used to calculate the azimuth and apparent velocity of the signal. These two parameters are thereafter used to estimate the epicenter latitude-longitude. All these parameters are estimated in near real time as soon as the P-phase of seismic signal reaches the detector(s). Data from Gauribidanur seismic array is used for demonstrating the efficacy of the proposed methodology.

This paper presents an Internal Model Based (IMC) tuned PI controller for real-time control of a coupled tank liquid level system. The IMC is a model based controller design technique. In present scenario the IMC Controller method is widely used in almost every process control industries as it allows good set point tracking along with sulky disturbance response especially for the process with a small time delay. In the present work the model of the coupled tank system has been developed based on system identification technique that employs least square error algorithm (LS) for parameter estimation. The proposed controller algorithm has been applied on the identified model. The performance of the proposed control algorithm has been compared with that of a Ziegler-Nichols tuned PI controller. From both the simulation as well as the experimental results, it is observed that the performance of the proposed PI control techniques is more efficient than the conventional PI controller which is tuned by Ziegler-Nichols approach.

The nonlinear nature of the system behavior causes several disturbances due to which the stability of the system gets affected. Controlled operation of power systems is very critical and most important factoris to achieve stable power system. For this reason there is a need of an adaptive control technique. PID controllers are widely used due to their simplicity and ease of re-tuning on-line. Several tuning methods such as Pattern Search (PS), Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Simulated Annealing (SA) are being used for the optimum setting of PID controller parameters so as to improve the system stability. In this paper the performance of PID controller tuned by different techniques is compared so as to design optimum controller.

In developing countries, patients with disabilities are often deprived of getting treated at rehabilitation centres with modern equipments and technologies. In India as per the 2011 census about 2.21% of the population suffer with disabilities due to either visual, auditory, speech or locomotor dysfunctions. Locomotor disability is seen predominantly in about 20.27% of patients amongst the various other disabilities. Measurement of the foot deformities is very essential for the fabrication of orthosis. The techniques of foot measurement that are presently used needs either the patient's foot outline measurement to be sent to the rehabilitation centre or cast measurement to be taken using plaster of paris mould. The need of the hour is for a technique that is quick and doesn't require the patient to visit the rehabilitation centre. This paper suggests a method in which the digital photograph of the foot outline of a remotely located patient would help to acquire the required dimensions of the foot. The developed technique of measuring foot outline has been validated by comparing n=103 pairs of digital photographs of patient's foot outline with that of the manual method of measurement. Error in measurement using this technique was found to be 2.83 ±0.39mm. Also Pearson correlation coefficient of measured foot length and width were 0.991±0.005 for a 95% Confidence Interval and was very significant (p<;0.001). Acquiring foot measurement of remotely located patients through these methods can help the clinical experts in the rehabilitation centre fabricate appropriate foot wear or orthotic device for the patient.

In this paper, ballistic missile tracking on re-entry has been considered. Position, velocity and ballistic coefficient are considered as states of the target. As no prior information about the target shape, mass and area is available, ballistic coefficient of the target has been considered as a state variable. Different type of nonlinear filters such as ensemble Kalman filter (EnKF), unscented Kalman filter (UKF), Gauss-Hermite filter (GHF), sparse-grid Gauss-Hermite filter (SGHF), cubature quadrature Kalman filter (CQKF) are used to estimate states of the target. The performance of all the above mentioned filters has been compared on the basis of estimation accuracy, computational time and missed distance. The 3 points GHF provides lowest miss distance at reasonably low computational time; so GHF-3 is recommended for this problem.

In recent years, installation of renewable energy facilities is increasing rapidly in response to the movement to suppress the release of greenhouse gasses responsible for the warming of the earth and to save fossil fuels, which are growing increasingly precious. Furthermore, the cost of photovoltaic systems is decreasing year by year. Therefore, it is assumed that price of photovoltaic power will be falling in the future. However, in Japan, the large amount of surplus electricity power from photovoltaic systems exerts a bad influence on the power grid. In this study, an EV charging station utilizing renewable energy is proposed as a business model. The proposed EV charging station purchases power from photovoltaic systems at a low price and uses that power to charge a fixed battery. Then the power is sold, being used to charge electric vehicles during the daytime. Moreover, the station can provide power to smart houses at an economical price when load demand is high. The effectiveness of the proposed EV charging station was verified with numerical simulations.

The paper presents a scheme for the rotor side field oriented control of doubly fed induction generator (DFIG) connected to the power grid. To control the speed, the slip power is exchanged between the grid and the generator through a Matrix Converter connected to the rotor side as power frequency changer. Use of Matrix Converter (MC) helps to increase the input power factor of the overall DFIG system. Based on stator flux oriented control, the dynamic modeling of entire system is implemented in the synchronously rotating reference frame (d-q). The scheme is able to control the active power from the rotor terminals and it also allows the sharing of magnetizing current between stator and rotor. The analysis of the entire scheme and the design of various controllers are discussed. The simulation results are presented to justify the proposed scheme before implementing the scheme in hardware.

In this paper a new method is proposed to assess the harmonic contributions of a customer in a non radial power system network. This method can determine whether the harmonic pollution at a particular bus in a power system network is due to the supply system or due to the consumer load. This method gives information about the location of harmonic source of pollution in the transmission line upstream or downstream the point of measurement. This strategy is able to detect the prevalent source of harmonic pollution during presence of more than one harmonic source. The dependence of the effectiveness of this method on the sampling frequency has been discussed in details.

In this paper, a control scheme for tracking maximum power point for a solar photovoltaic (PV) panel feeding power to the three phase grid through an intermediate boost converter followed by a grid-tie PWM inverter stage is presented. The intermediate DC to DC boost converter small signal model is derived considering the fact that its output behaves as a constant DC voltage power sink. The selection criteria for the inductor value for continuous current mode operation and the capacitor at the PV panel output are discussed at length. A separate controller, in addition to the maximum power point tracking (MPPT) controller, is designed for the boost converter based on its derived model to set the current value for maximum power point tracking and presented. A method is also described here for choosing the sampling instances for getting average inductor current in a cycle corresponding for MPPT without using a filter. The analytical findings and simulation results are well agreeing.
