Identification and Control in Rotor Systems, Second Edition

The second volume of the second edition of the Rotor Systems book focuses on identification techniques in rotor systems. It provides comprehensive coverage of unbalance identification and bearing dynamic parameter identification algorithms. Additionally, it explores the sensors and exciters used in rotor systems, along with the associated signal conditioning equipment. The book delves deeply into error analysis, offering detailed discussions to help readers understand measurement errors and their implications. Furthermore, the control of rotor systems is thoroughly addressed, including the analysis of both simple and multi-degree-of-freedom (multi-DOF) rotor systems. This edition also expands on experimentation related to the flexible balancing of rotors, providing practical insights into advanced rotor system control techniques.

• Covers balancing of rigid and flexible rotors with solved examples
• Describes various sensors and exciters used in rotor system and related signal conditioning equipment
• Explores signal processing with special focus on the full spectrum relevant for rotor response analysis
• Contains basic information on the condition monitoring of various types of rotating machinery
• Reviews control of rotor system includes analysis of simple and multi-DOF rotor system

This book is aimed at senior undergraduate/graduate students in mechanical engineering, rotor dynamics, rotating machinery/turbomachinery, and related fields.

Rajiv Tiwari was born in 1967 at Raipur in Madhya Pradesh. India. He graduated in B.E. in 1988 (Mechanical Engineering) from Ravishankar University, Raipur and M. Tech. (Mechanical Engineering) in 1991 and Ph. D. (Mechanical Engineering) in 1997 from Indian Institute of Technology (IIT) Kanpur, India. He worked as Research Officer at University of Wales, Swansea, UK for one year in 2001 on deputation. He was elevated to Associate Professor in 2002 and to Professor in 2007 at IIT Guwahati. He has been deeply involved in research area of Rotor Dynamics (i.e. especially on Identification of mechanical system parameters, e.g. the bearings, seals and rotor crack dynamic parameters, Fault diagnosis of machine components like bearings, gears, pumps, and induction motor and application of active magnetic bearings in condition monitoring of rotating machinery). His research area also includes rolling element bearing design and analysis for high-speed applications. He has completed three projects from Aeronautical Research & Development Board (ARDB), India on these topics. He has been offering consultancy for last several years to Indian industries like Indian Space Research Organisation (ISRO), Trivandrum; Combat Vehicle R&D Establish (CVRDE) Chennai; Tata Bearings, Kharagpur; apart from other local industries in the northeast of India. One of the European power industries the Skoda Power, Czech Republic has also taken consultancy of seal dynamic parameter estimation for steam turbine applications. Dr. Tiwari has been author of over 130 Journal and Conference papers.
