The design and implementation of the Linear-Proportional Integral Derivative (L-PID) controller and Integer Order-Proportional Integral Derivative (IO-PID) controller on a benchmarked Twin Rotor MIMO system (TRMS) for experimental verification of their trajectory tracking capabilities are presented in this paper. These controllers have been implemented experimentally for controlling pitch and yaw angles of the TRMS. IO-PID controller have been described and its parameters are modified and adjusted using the nonlinear interior point optimization (fmincon) method to minimize the cost function of the controller parameters. TRMS yaw and pitch trajectory responses with these controllers are obtained and tested experimentally at distinct intervals with disturbances. It is observed that IO-PID controller will give better trajectory tracking performance as compared with L-PID controller.

This paper performs reliability analysis to achieve an undesirable trade-off among the current ratings, efficiency, and reliability of power modules in Voltage Source Converters (VSC). It investigates the aspects of reliability for Silicon Carbide (SiC) power modules, and estimate the lifetime, failure rate and efficiency of the power electronic converters used in a three-phase grid connected photovoltaic system. The reliability analysis is carried out by performing Ideal Component Testing (ICT), and Active Component Testing (ACT) under four different operating modes. The probability rate of the system failure for each operating mode is calculated using Markov chain process. Finally, the dependency of reliability and lifetime on the gate voltage is identified and the necessary measures are suggested to achieve an undesirable trade-off among the targeted current ratings, efficiency, and system reliability.

With rising environmental concerns due to tailpipe emissions of present-day vehicles on Indian roads, industry is looking to introduce alternative modes of transportation. Driving Electric Vehicles will reduce the overall carbon footprint only if the batteries are charged from renewable energy. With its falling prices and ease of installation, Photovoltaic systems are ideal candidate for charging Electric Vehicles.

This paper focus on developing a new islanding detection method with the help of machine learning and signal processing technique. The islanding detection method make sure that there is a proper remote monitoring of the grid integrated photovoltaic (PV) system. In case of grid fault or maintained of the grid, a proper informed signal is provided to various distributed generation (DG) networks so that they can disconnect with the grid and operate in isolated mode. A simulation of 1kW grid connected PV system is performed. The signal such as voltage, current and frequency are recorded at point of common coupling (PCC). The feature of recorded signals are extracted using wavelet transformation. The extracted features are used to form a islanding scenarios matrix. The matrix is further utilized to train a classifier using machine learning algorithm. From the result it can be observed that the trained classifier depicted 97.9% training accuracy with a training time of 16.9 sec which is better when compared with the literature. Further the trained classifier is subjected to test with an unknown islanding condition to observe the robustness of the classifier.

The key role of fault detection and diagnosis in the nonlinear system is to maintain safety, reliability, and survivability in case of system failure during a fault. The main idea behind this paper is to explore unmanned surface vehicles (USVs) performance under faulty conditions. K-Nearest Neighbour method has been chosen for faults detection, identification, and classification. A ball balancer system, which is a laboratory setup, has been considered for analysis of faults occur. The translational motion-related control of USVs is represented by ball movement on a plate in the x-y direction. The sway motion of USVs corresponds to x-axis movement of the ball while surge represents the y-axis motion of the ball on a plate. For algorithm implementation, the necessary fault data has been taken from the position of the ball, plate angle, and motor input voltage after inserting the fault in the system. For performance analysis, the results of Simulink and hardware has been validated.

With the continuous increase in demand for electrical energy, power electronics is becoming an important aspect of our lives. Renewable energy sources like Solar and Wind are helping a lot in reducing this ever-increasing demand for electrical energy besides being cheap and clean. Conventional two-level inverters used for converting DC output from renewable energy sources to AC waveform contains a lot of harmonics and are replaced by Multilevel Inverters (MLI). MLI’s are gaining more and more interest in researchers these days because of small harmonic distortion and low switching frequency operation. In this paper, a Two-winding Multitapped transformer (TWMTT) based nine-level inverter is discussed in detail along with its switching sequence and its comparison with other prominent topologies of nine-level inverters is also drawn. On implementing this topology in MATLAB/Simulink, total harmonic distortion (THD) was found to be 9.37% which is very low compared to other topologies for nine-level inverters.

Decentralized control is an effective method for stabilization of interconnected systems. The sliding surface is selected such that the effect of the unmatched perturbation becomes minimum. Coupled pendulums are a benchmark system to verify the effectiveness of the robust controller. The robustness properties of the high gain observer based Sliding mode control is utilized for stabilization of interconnected systems such as Coupled pendulums. Simulation results show the effectiveness of high gain observer based sliding mode control by considering various uncertainties.

The rapid growth in Multimedia application over the Internet has put considerable pressure on existing hardware system for information transmission and retrieval over the bandlimited channel. To deal with huge data volume of multimedia application, image coding is a viable solution. This paper proposed image coding scheme based on dual tree complex wavelet transform (DT-CWT). DT-CWT exploit the directionality and shift invariant property to compact the pixel energy in few wavelet coefficients. The transform coefficients are encoded using simple Embedded Block truncation coding scheme (EBCOT) and experiment results demonstrates that the rate-distortion results outperforms to the state-of-the art JPEG 2000 standard at low bit-rate, particularly for images with strong directional features

This paper proposes a single-source boost multilevel inverter topology with inherent voltage balancing feature. The proposed topology is synthesized by a combination of the conventional boost converter and diode-capacitor voltage multiplier circuit (VMC). The diode-capacitor VMC is capable to solve the capacitor voltage balancing problem and step-up the input voltage to the required level of dc link voltage. The proposed converter can provide variable fractional voltage gain, which is a key requirement to achieve the maximum power point (MPP) in a photovoltaic application. Zero-voltage-switching is achieved for the high-frequency switch, which mitigates switching losses. A hardware prototype of the proposed seven-level inverter is developed and the results obtained from the experimental prototype are demonstrated to validate the performance of the proposed converter.
