The textbook is for a one-semester graduate course on flight control, and includes the student version of the CONDUIT (Control Designer's Unified Interface) software. The design approach is based on multi-objective parametric optimization, say the authors, but readers who use a different design method will still find the book a useful compendium of well-validated flight control principles and rules-of-thumb. They also suggest that practicing aircraft and rotorcraft flight dynamics and control system engineers could use the material to challenge and improve their flight control processes.

Recenzijos

"The authors have created not only an indispensable guide and set of examples for CONDUIT(R), but also a remarkably complete planning document, checklist, and text for any flight control design effort." -- John Hodgkinson, aircraft handling-qualities expert and author "An excellent flight control textbook for senior undergraduate and/or graduate students, with a very well-balanced perspective covering the theory, implementation, and practical applications." -- Professor Kamran Turkoglu, Aerospace Engineering, San Jose State University

Historical flight control design case studies and lessons learned, and best practices in selecting control law architecture, specifications, and simulation modeling. Multi-objective parametric optimization design approach, with a focus on how to apply this method to both simple case studies and real-world piloted simulation and flight-test examples. Optimization of classical and modern MIMO control design methods to meet a common set of design requirements and compare the resulting performance and robustness. Step-by-step illustrations of all methods using practical case studies covering the entire design cycle, from selection of design specifications and simulation model to optimization results and robustness analysis. Specific guidelines for specification selection, simulation modeling, control design rules of thumb, robustness analysis, nested-loop architecture optimization, and design margin optimization. Extensive problem sets and a solution guide for classrooms or self-study, giving hands-on real-world experience with methods and results. Student version of CONDUIT(R) for exercises is included.
