This book, written by two major figures in adaptive control, provides a wealth of material for researchers, practitioners, and students. While some researchers in adaptive control may note the absence of a particular topic, the book‘s scope represents a high-gain instrument. It can be used by designers of control systems to enhance their work through the information on many new theoretical developments, and can be used by mathematical control theory specialists to adapt their research to practical needs. The book is strongly recommended to anyone interested in adaptive control.

Adaptive Control

This paper provides a comprehensive survey on the state-of-the-art condition monitoring and fault diagnostic technologies for wind turbines (WTs). The Part I of this survey briefly reviews the existing literature surveys on the subject, discusses the common failure modes in the major WT components and subsystems, briefly reviews the condition monitoring and fault diagnostic techniques for these components and subsystems, and specifically discusses the issues of condition monitoring and fault diagnosis for offshore WTs.

A Survey on Wind Turbine Condition Monitoring and Fault Diagnosis—Part I: Components and Subsystems

A review on wind turbine control and its associated methods

There is a constant call for reduction of operational and maintenance costs of induction motors (IMs) These costs can be significantly reduced if the health of the system is monitored regularly This allows for early detection of the degeneration of the motor health, alleviating a proactive response, minimizing unscheduled downtime, and unexpected breakdowns The condition based monitoring has become an important task for engineers and researchers mainly in industrial applications such as railways, oil extracting mills, industrial drives, agriculture, mining industry etc Owing to the demand and influence of condition monitoring and fault diagnosis in IMs and keeping in mind the prerequisite for future research, this paper presents the state of the art review describing different type of IM faults and their diagnostic schemes Several monitoring techniques available for fault diagnosis of IM have been identified and represented The utilization of non-invasive techniques for data acquisition in automatic timely scheduling of the maintenance and predicting failure aspects of dynamic machines holds a great scope in future

Condition Monitoring and Fault Diagnosis of Induction Motors: A Review

Validation of an integral sliding mode control for optimal control of a three blade variable speed variable pitch wind turbine

The aim of the present work is to bring out an exergy analysis of the hydrocarbon refrigerant mixture of R290/R600a as an alternative to R134a on the performance of a domestic refrigerator which is originally designed to work with R134a. The performance of both refrigerants was evaluated using an exergy analysis. The effects of evaporator temperature on the coefficient of performance (COP), exergy loss, exergic efficiency, and efficiency defect in the four major components of the system for R134a and R290/R600a mixture were experimentally investigated. The results obtained showed that the COP of R290/R600a mixture was improved up to 28.5 % than that of R134a. The highest average exergic efficiency of the system (42.1 %) was obtained using R290/R600a mixture at an evaporator temperature of 263 K (−10 °C). The overall efficiency defect in the refrigeration cycle working with R290/R600a mixture was consistently better than R134a.

Summary The main objectives of this paper is aimed to control the position of a field oriented Induction Servo motor drive for a given reference input signal in a very efficient way and to compare the two control schemes using Matlab/Simulink. To design a total sliding-mode control system which is insensitive to uncertainties, including parameter variations and external disturbances in the whole control process. To design an adaptive sliding-mode control system which adjusts the bound of uncertainities in real time and also reduces the chattering phenomena in the control effort using a simple adaptive algorithm? The simulation result of the control schemes for a given Induction Motor is discussed below.

Sliding Mode Control of Induction Motor using Simulation Approach

Simulation of Sensor Fault Diagnosis for Wind Turbine Generators DFIG and PMSM Using Kalman Filter

The Multilevel inverter is emerging as a new breed of power inverter option for high power applications, Especially for FACTS controllers. This can create high voltage and reduce harmonics by its own circuit topology. The power levels of the inverter are largely restricted by carrier frequency. For air cooled design the frequency is practically limited to 3 to 5 KHz for large inverters, hence to increase power level it is proposed to operate two inverters in parallel with phase shifted carrier. The equivalent carrier frequency can be doubled and the output harmonics will be reduced here in this paper simulation of various carrier based PWM methods had been explained. Results and comparison also discussed.
