Modelling and Control of Mini-Flying Machines is an exposition of models developed to assist in the motion control of various types of mini-aircraft: • Planar Vertical Take-off and Landing aircraft; • helicopters; • quadrotor mini-rotorcraft; • other fixed-wing aircraft; • blimps. For each of these it propounds: • detailed models derived from Euler-Lagrange methods; • appropriate nonlinear control strategies and convergence properties; • real-time experimental comparisons of the performance of control algorithms; • review of the principal sensors, on-board electronics, real-time architecture and communications systems for mini-flying machine control, including discussion of their performance; • detailed explanation of the use of the Kalman filter to flying machine localization. To researchers and students in nonlinear control and its applications Modelling and Control of Mini-Flying Machines provides valuable insights to the application of real-time nonlinear techniques in an always challenging area.
Indoor Navigation Strategies for Aerial Autonomous Systems presents the necessary and sufficient theoretical basis for those interested in working in unmanned aerial vehicles, providing three different approaches to mathematically represent the dynamics of an aerial vehicle. The book contains detailed information on fusion inertial measurements for orientation stabilization and its validation in flight tests, also proposing substantial theoretical and practical validation for improving the dropped or noised signals. In addition, the book contains different strategies to control and navigate aerial systems. The comprehensive information will be of interest to both researchers and practitioner...
In this account of the naval aspect of Hernando Cortés's invasion of the Aztec Empire, C. Harvey Gardiner has added another dimension to the drama of Spanish conquest of the New World and to Cortés himself as a military strategist. The use of ships, in the climactic moment of the Spanish-Aztec clash, which brought about the fall of Tenochtitlán and consequently of all of Mexico, though discussed briefly in former English-language accounts of the struggle, had never before been detailed and brought into a perspective that reveals its true significance. Gardiner, on the basis of previously unexploited sixteenth-century source materials, has written a historical revision that is as colorful ...
This volume of the "Inter-American Yearbook on Human Rights" covers the year 1989, and contains all the documents and information (in English and Spanish) concerning the activities of the Organization of American States in the field of the promotion and protection of human rights. Like its predecessors, this "Yearbook" aims to contribute to a greater awareness of the functions and activities of the organs of the Inter-American system for the protection of Human Rights.
In ‘Another Jerusalem’: Political Legitimacy and Courtly Government in the Kingdom of New Spain (1535-1568) José-Juan López-Portillo offers a new approach to understanding why the most densely populated and culturally sophisticated regions of Mesoamerica accepted the authority of Spanish viceroys. By focusing on the routines and practices of quotidian political life in New Spain, and the ideological affinities that bound indigenous and non-indigenous political communities to the viceregal regime, López Portillo discloses the formation of new loyalties, interests and identities particular to New Spain. Rather than the traditional view of European colonial domination over a demoralized indigenous population, New Spain now appears as Mexico City’s sub-empire: an aggregate of the Habsburg ‘composite monarchy’. "Embellished with wonderful illustrations, this work draws upon extensive secondary and primary sources. Scholars studying Spain's America will find it a thoughtful addition to historical literature on 16th-century New Spain." - M. A. Burkholder, University of Missouri - St. Louis, in: CHOICE, July 2018 Vol. 55 No. 11
