Описание: By establishing an alternative foundation of control theory, this thesis represents a significant advance in the theory of control systems, of interest to a broad range of scientists and engineers. While common control strategies for dynamical systems center on the system state as the object to be controlled, the approach developed here focuses on the state trajectory. The concept of precisely realizable trajectories identifies those trajectories that can be accurately achieved by applying appropriate control signals. The resulting simple expressions for the control signal lend themselves to immediate application in science and technology. The approach permits the generalization of many well-known results from the control theory of linear systems, e.g. the Kalman rank condition to nonlinear systems. The relationship between controllability, optimal control and trajectory tracking are clarified. Furthermore, the existence of linear structures underlying nonlinear optimal control is revealed, enabling the derivation of exact analytical solutions to an entire class of nonlinear optimal trajectory tracking problems. The clear and self-contained presentation focuses on a general and mathematically rigorous analysis of controlled dynamical systems. The concepts developed are visualized with the help of particular dynamical systems motivated by physics and chemistry.

Описание: X-by-wire Unmanned Ground Vehicles (UGVs) have been attracting increased attention for various civilian or military applications. The x-by-wire techniques (drive-by-wire, steer-by-wire, and brake-by-wire techniques) provide the possibility of achieving novel vehicle design and advanced dynamics control, which can significantly improve the overall performance, maneuverability, and mobility of the UGVs. However, there are few full x-by-wire UGVs prototype models reported in the world. Therefore, there is no book that can fully describe the design, configuration, and dynamics control approach of full x-by-wire UGVs, which makes it difficult for readers to study this hot and interesting topic.In this book, we use a full x-by-wire UGV, developed by our group, as the example. This UGV is completely x-by-wire with four in-wheel motors driven and a four-wheel independent steer steer. In this book, the overall design of the UGV, the design of the key subsystems (battery pack system, in-wheel motor-driven system, independent steer system, remote and autonomous control system), and the dynamics control approach will be introduced in detail, and the experiment's results will be provided to validate the proposed dynamics control approach.

Dynamics and Advanced Motion Control of Unmanned Ground Off-Road Vehicles details both theoretical concepts such as planning and perception when working with UGVs, as well as more practical, hands-on aspects such as torque vectoring control. The book also covers related technologies such as intelligent and electrification of ground vehicles. After an introduction, initial chapters include an exploration of wheel-soil and track-soil interaction mechanisms, motion stability, motion control, fault detection and identification, and fault tolerance control. This book offers readers a detailed understanding of Unmanned Ground Vehicles by combining theory, applications and further developments.
Topics are covered in such a way that readers will be well versed on the current field of UGVs and will be able to implement future design and research in a feasible and effective way.

The algorithms presented in this book were designed to achieve an acceptable trade-off between contradictive requirements to the software of small UAV navigation systems: sufficient accuracy and reliability in order to perform required flight missions on the one hand, and acceptable cost and simplicity of this software on the other hand. The core of modern navigation systems is integrated Strapdown Inertial Navigation System (SINS) and GPS, so in this book, the SINS algorithms and the algorithms of sensor fusion are described primarily. Inertial sensors (rate gyros and accelerometers) used in SINS are manufactured on the basis of the MEMS-technology. That is why they possess poor accuracy and need to be corrected with other sensors (GPS, magnetometers, and barometric altimeters). It is necessary to take into account that flight missions of small UAVs are characterized by small flight distances, small flight times, small flight speeds, etc. These properties of small UAV flight missions and properties of MEMS-sensors create a practical background for simplification of the SINS algorithms, simultaneously preserving their accuracy at acceptable levels. The navigation algorithms for gyro-free SINS are also considered. Increasing reliability of the UAV navigation systems requires a solution of the problems of the detection of the faulty sensors. These algorithms are described. Some practical aspects of the operation of navigation systems such as initial alignment, sensors calibration, and laboratory, ground, and flight testing of integrated SINS for small UAVs are also presented.
This book will be useful for a wide circle of researchers, engineers, and graduate students involved in modern UAV design and manufacturing.
