Volume 1 • Issue 1 • 1000e105 J Aeronaut Aerospace Eng ISSN:2168-9792 JAAE, an open access journal Open Access Editorial Open access journals become more and more reliable and popu- lar among professionals and beginners like PhD students. As opposed to closed journals, they provide unrestricted and permanent access to scientifc publications, may also be included in conventional index and abstract databases. Many Open Access journals also provide rigorous peer review for high quality of publications. Is the Journal of Aeronautics and Aerospace Engineering a proper one to be open access? Te question may seem trivial. I think it is not, if one thinks about its scope and the potential impact of new fndings and their dissemination across aerospace and related disciplines, and maybe across felds seemingly not related with aerospace at all. Specifcally, the scope of the Journal of Aeronautics and Aerospace Engineering that addresses various felds of aeronautical sci- ences, electrical and mechanical engineering, rocket science, aircraf and rocketry, and related domains as control encompasses the leading research that gears new theoretical developments and technologies and opens wider perspectives and new ground for theoretical and applicable results in other scientifc areas. Te aeronautical science is the source of bold ideas that may infuence progress in science and technology. Tere are many examples of impacts of aeronautics related research results on other felds of science. One example is from the domain of nonlinear optimal control. Its rapid development in 1950s and 1960s together with algorithms and reliable codes for these algorithms, for calculating nonlinear optimal trajectories for aircraf and spacecraf was forced by practical needs. Te well known problem that had to be solved at that time was construction of a spacecraf reentry trajectory. Some of the frst numerical solutions for optimal spacecraf trajectory problems were given in 1950s [1,2]. Tese solutions used the shooting method of guessing initial values of Lagrange multipliers when inte- grating the Euler-Lagrange equations forward and then interpolating on the multipliers until the fnal conditions are satisfed. Tis approach is usually not applicable to aircraf trajectories, i.e. not to non-con- servative systems because of the lost of numerical stability. Gradient methods, which were proposed; see e.g. in [3] and references in [4], eliminated the instability problem. According to Bryson [5], one of the frst applications of the gradient method to spacecraf and aircraf were made about 1960s. More details about the fascinating development of the nonlinear optimal control under the pressure of the aeronautical research and applications can be found in [5] and references there. As the result of eforts of many engineers and scientists working for aeronautics, nowadays many disciplines enjoy efective optimal control strategies and algorithms, and continue their developments for their specifc needs and applications. Tey are for example, economy, invest- ment and business sciences, management, manufacturing in the design and operation of production processes, and other engineering and non- engineering areas. Another example is not so pronouncing, not so spectacular, and related to personal experience of a single researcher. However, I think many of us, researchers, may share this experience. Let me, as a me- chanical engineer from an aeronautical department, as a university researcher and teacher, whose research concentrates on dynamics, modeling and nonlinear control, share some example from my own experience. For some years of my university career, I worked on modeling and control strategies for nonholonomic systems. Traditionally, nonlinear control uses dynamic models based mostly upon Lagrange’s equations with multipliers. Te scope of applications of these equations is limited, because only frst order constraints, material or generated by conserva- tion laws, may be merged into these dynamic models. Requirements for motion that are ofen specifed by equations for controlled systems are not merged into these equations. First order constraints that are adjoined to the equations of motion via the introduction of Lagrange multipliers can also be embedded through the reduction procedure, which avoids the addition of auxiliary variables. To obtain a dynamic control model, a reduction procedure has to be applied to eliminate the multipliers. In some latest monographs one may fnd some eforts of “leaving the Lagrange equations approach” but no constructive model- ing methods and application examples can be found there, see, e.g. [6]. I have generated and suggest to apply for nonlinear control appli- cations the generalized programmed motion equations, which might be derived in various coordinates, e.g., generalized or quasi, and which furnished a unifed framework for dynamic modeling systems sub- jected to nonholonomic equality constraints of arbitrary order [7]. Te fnal application of the framework is the development of a new tracking strategy, which is referred to as the model reference tracking control for programmed motion. It is dedicated to tracking tasks specifed by equations of programmed constraints. Te strategy provides a unifed approach to motion tracking for both holonomic and nonholonomic mechanical systems. Te framework and the tracking strategy ft mul- tibody systems, either moving on the ground, in water or fying. So it might be of interest for control, robotic, and maybe aeronautical com- munity. It was my individual research and I expected some feedback, not only next scientifc degree.
