Book Description
This book gives in a concise and easy to understand form the various aspects of Practical Design of Flight Control Systems for Launch Vehicles and Missiles. It covers almost every aspect of Flight Control System Design which a designer would like to know, such as mission considerations, control requirements for various segments of the flight trajectory and different types of control effectors. It further gives generalized equations of motion with a novel method of incorporating structural flexibility and propellant sloshing which does not require rederivation, and very easy and common sense approach to deriving slosh and gimballed engine dynamic equations. Subsequently it gives the control system configurations, power plant sizing, loop design for linearised system and detailed analysis and design of on-off reaction control systems. It also covers various software features which are necessary for actual implementation of the design in flight missions, robustness features to avoid malfunctioning in some circumstances, design validation aspects including end-to-end sign checks and describes some flight experiences which called for design updates. The book is unique for its strong practical flavour and is directly useful to the working engineers in the field and post graduate students in Aerospace Engineering.

Book Description
This book is an essential guide to nonlinear dynamics and vibration control, detailing both the theory and the practical industrial applications within all aspects of engineering. Demonstrating how to improve efficiency through reducing unwanted vibration, it will aid both students and engineers in practically and safely improving flexible structures through control methods. Increasing demand for light-weight robotic systems and space applications has actuated the design and construction of more flexible structures. These flexible structures, involving numerous dynamic systems, experience unwanted vibrations, impacting accuracy, operating speed, safety and, importantly, efficiency. This book aids engineers in assuaging this issue through vibration control methods, including nonlinear dynamics. It covers topics such as dynamic modeling of nonlinear system, nonlinear oscillators, and modal analyses of multiple-mode system. It also looks at vibration control methods including linear control, nonlinear control, intelligent control, and command smoothers. These control methods are effective and reliable methods to counteract unwanted vibrations. The book is practically minded, using industrial applications throughout, such as bridge cranes, tower cranes, aerial cranes and liquid sloshing. It also discusses cable-suspension structures, light-weight links, and fluid motions which exhibit flexible-structure dynamics. The book will be of interest to students and engineers alike, in the field of mechatronics, mechanical systems and signal processing, nonlinear dynamics, vibration, and control engineering.

Book Description
This book described vibration reduction for flexible structures by the command smoothing techniques. The Command smoothing technique is a kind of open-loop controller. The operator's commands filter through a piecewise continuous function, called smoother, to produce smoothed commands. Smoothed commands move flexible dynamic systems toward desired positions with minimal oscillations. Five types of command smoother were reported including one-piece, two-pieces, three-pieces, and four-pieces smoothers, and the smoother for multi-mode Duffing oscillators. All smoothers are robust to changes in the system parameters and working conditions. The command smoothing technique has been successfully applied to industrial cranes, sloshing suppression, flexible manipulators, high-speed cam and follower systems, and helicopter slung loads.
