A complete dynamic model of flight dynamics is presented. Based on this model, the inverse problem and that of the synthesis of programmed motion are solved. A new approach to decoupled control of large-scale nonlinear systems is applied to dynamic flight control. Control synthesis is performed in two steps. First the nominal programmed control is synthesized using the complete model of flight dynamics. This nominal control should realize nominal trajectory under ideal conditions with no perturbations. At the second step the tracking of nominal trajectory is realized. The system is viewed as a set of decoupled subsystems and for each subsystem local control is synthesized. Then the stability of the overall system is analyzed and global control is introduced to compensate coupling among some of the subsystems. In the book a particular choice of subsystems is proposed in a case of flight control, and the local and global control synthesis is presented. Extensive simulations of flight control with different control laws are also presented.

Here for the first time in one book is a comprehensive and systematic approach to the dynamic modeling and control of biped locomotion robots. A survey is included of various approaches to the control of biped robots, and a new approach to the control of biped systems based on a complete dynamic model is presented in detail. The stability of complete biped system is presented for the first time as a highly nonlinear dynamic system. Also included is new software for the synthesis of a dynamically stable walk for arbitrary biped systems, presented here for the first time. A survey of various realizations of biped systems and numerous numerical examples are given. The reader is given a deep insight into the entire area of biped locomotion. The book covers all relevant approaches to the subject and gives the most complete account to date of dynamic modeling, control and realizations of biped systems.

During the period 1982-1985, six books of the series: Scientific Fun­ damentals of Robotics were published by Springer-Verlag. In chronolo­ gical order these were: Dynamics of Manipulation Robots: Theory and Application, by M. Vukobra­ tovic and V. Potkonjak, Control of Manipulation Robots: Theory and Ap­ plication, by M. vukobratovic and D. Stokic, Kinematics and Trajectory Synthesis of Manipulation Robots, by M. Vukobratovic and H. Kircanski, Real-Time Dynamics of Hanipulation Robots by M. Vukobratovic and N. Kircanski, Non-Adaptive and Adaptive Control of Manipulation Robots, by M. Vukobratovic, D. Stokic and N. Kircanski and Computer-Aided De­ sign and Applied Dynamics of Manipulation Robots, by M. Vukobratovic and V. Potkonjak. Within the series, during 1989, two monographs dealing with new sub­ jects will be published. So far, amongst the published monographs, Vol. 1 has been translated into Japanese, Volumes 2 and 5 into Russian, and Volumes 1-6 will appear in Chinese and Hungarian. In the author's opinion, the afore mentioned monographs, in principle, cover with sufficient breadth, the topics devoted to the design of ro­ bots and their control systems, at the level of post-graduate study in robotics. However, if this material was also to apply to the study of robotics at under-graduate level, it would have to be modified so as to obtain the character of a textbook. With this in mind, it must be noted that the subject matter contained in the text cannot be simpli­ fied but can only be elaborated in more detail.

The first book of the new, textbook series, entitled Applied Dynamics of Manipulation Robots: Modelling, Analysis and Examples, by M. Vukobratovic, published by Springer-Verlag (1989) was devoted to the problems of dynamic models and dynamic analysis of robots. The present book, the second in the series, is concerned with the problems of the robot control. In conceiving this textbook, several dillemas arouse. The main issue was the question on what should be incorporated in a textbook on such a complex subject. Namely, the robot control comprises a wide range of topics related to various aspects of robotics, starting from the syn­ thesis of the lowest, executive, control level, through the synthesis of trajectories (which is mainly related to kinematic models of robots) and various algorithms for solving the problem of task and robot moti­ on planning (including the solving of the problems by the methods of artificial intelligence) to the aspects of processing the data obtai­ ned from sensors. The robot control is closely related to the robot pro­ gramming (i. e. the development of highly-specialized programming lan­ guages for robot programming). Besides, numerous aspects of the con­ trol realization should be included here. It is obvious that all these aspects of control cannot be treated in detail in the frame of a text­ book.
