In this paper a novel digital phase lock loop (DPLL) is introduced with Teager energy operator (TEO) incorporated discrete energy separation algorithm DESA2. The output of the DESA2 is controlled using genetic algorithm (GA) optimized fuzzy controller. The input and output membership functions are optimized using GA along with the input and output controller gains of the fuzzy controller. This kind of approach to design a DPLL is a new idea in the signal processing and DPLL design.

In order to avoid large scale failure, it is necessary to monitor the widespread and complex performance of interconnected power grid system in real time. In case of bulk power system, the operation of Protective Relays and the Circuit Breakers are fast enough for secured performance but tracking of the system parameters during an event is beyond the scope of such devices. So, real time tracking before an event and quick analysis for potential failure of the system at the time of disturbances is quite difficult. Modernization of technology provides us with instruments to sample the continuous-time analog signal into discrete-time digital signal with the help of a device called Phasor Measuring Unit (PMU). As a result, it is also possible to estimate the dynamic phasor of the system and to determine the frequency and the Rate of Change of Frequency (ROCOF) of the system within a specific frequency zone. The purpose of this paper is to present a mechanism for continuous observation of the interconnected power system within a specific frequency zone and detection of its nature with improved accuracy using Phasor Measuring Unit (PMU). Having the Rate of Change of Frequency as the prime detector of disturbances at the interconnected grid system in Gaussian plane, this should facilitate the continuous observation and a system protection scheme which is more efficient. This should minimize the sudden damages of the system equipments due to abnormal behavior of the bulk interconnected electrical power system.

Sliding mode controllers of first and second orders have been designed for linear motion tracking for an eletrohydraulic actuation system having deadband and other nonlinear features like cylinder stiction, hysterisis and Stribeck characteristics. An input linearized structure has been developed to formulate sliding mode controllers, or SMC, of orders 1 and 2 for the nonlinear system. The applied SMC is coupled with a simple integral compensator for attenuating both the chatter of the input signal and any steady state error of the output. Real-time experiments have been carried out that show the first-order controller as better above 1.4Hz tracking and the second-order controller as better below 1.4Hz.

Nuclear facilities need very strict security mechanism to prevent unauthorized persons from gaining access to critical facility or approaching close enough to harm the facility. Physical Access Control System plays an important role in ensuring the entry of authorized personnel into the premises. There are so many ways by which this system can be designed and implemented, wherein the authenticity of the personnel can be verified including the photograph. Authentication process might be a multi factor with minimum of two factor authentication depending upon the critical nature of the facility. The paper presents how a novel embedded system based on BeagleBone Black evolved to authenticate the personnel by reading the credentials from the RFID based Identity card, fetching the photograph from the database and displaying on the monitor for positive identification of the photograph by the security personnel.

In an interconnected power system, both frequency and tie-line power exchange vary as load demand varies randomly. In this paper, a robust controller is designed to reduce the frequency deviations and tie line power error due to different load disturbances in multi-area interconnected power system. The robust H-infinity (H∞) controllers are designed both for two area power system with two reheat turbine units and three-area power system with non-reheat, reheat, and hydro turbine units. Using the concept of Linear Matrix Inequality (LMI), H∞ design specification has been realized and LMI approach has been used for the design of output-feedback H∞ controller. The resulting controller gives the robust performance in presence of parameter variations and other uncertainties. The performances of the controller is also compared with the performance of Robust Distributed Model Predictive Controller (RDMPC).

This paper presents prototype development of a three-phase bridge inverter for PV applications using dSPACE 1104 hardware interface with Matlab/Simulink software. It is evident that a PV system requires an inverter to generate ac power to make it available to the consumers at the utility. Firstly, the three-phase inverter model is built in Matlab Simulink and the control strategy used is current controlled SPWM. The generated PWM signals in Matlab Simulink from the voltage command of the load side are also obtained in real time using dSPACE 1104 control board. These signals are then applied to the gate of the power devices through proper driver circuits. The results obtained after implementing the entire set-up in the lab are presented here.

Phase Change Materials (PCMs) are being used in thermal energy storage systems because of their high energy storage density, and heat storage/release in small temperature range near melting temperature. Such requirements compel to design and develop materials with high latent heat of fusion for thermal energy storage applications. This will rely on characterization of materials to understand their thermal properties as a function of temperature. In this work, an experimental set-up is presented for measuring the thermodynamic properties of materials, such as, temperature-time response, latent heat of fusion, specific heat of solids and liquids, melting-solidification temperatures, degree of supercooling and enthalpy-temperature response of PCMs. The present experimental test set-up, including specific PCM container, is designed and fabricated for characterization of low temperature PCMs with melting temperature in the range of 0-100°C.

The model of a quadrotor is nonlinear and dynamically unstable due to the high level of system nonlinearity and external disturbances. In this paper a robust second order sliding mode controller has been proposed for altitude tracking of a quadrotor. The controller is derived using Lyapunov stability approach and proved theoretically asymptotic stability. The performance of proposed control method is evaluated by comparing the performance with conventional sliding mode control from the literature. It is demonstrate that the proposed second order sliding mode control improves the tracking control performance with better transient performances.

High level of uncertainty present in the movement of an object in manoeuvering target tracking problem makes the system hard to model. Such a system is nonlinear as well due to the irregularity present in the availability of radar measurements. A conventional particle filter designed for this problem has the limitation of sample loss, which can be handled effectively by an evolutionary strategy based particle filter. Such filter can tackle complex nonlinear system such as the one just described, but its performance suffer for dealing with larger number of particles. Present work investigates one task scheduling scheme among processors, which helps in improving the estimation accuracy of one evolutionary particle filter by incorporating more measurements in its computation.

This paper deals an adaptive fault tolerant control for active suspension in the presence of actuator saturation. An adaptive state-feedback controller is designed to tackle the issue of actuator fault. A Disturbance observer is utilized to observe the lumped disturbance. The partial actuator fault or actuator inefficiency is consider as an actuator fault. The fault is estimated and then compensated by the use of adaptive state feedback control law. The proposed controller is verified by the simulation.
