Distributed Analytical Formation Control and Cooperative Guidance for Gliding Vehicles

This paper addresses the analytical formation control and cooperative guidance problem for multiple hypersonic gliding vehicles under distributed communication. The gliding flight of the hypersonic gliding vehicle is divided into formation control phase and time coordination phase. In formation control phase, based on the idea of path tracking, the formation controller is designed using the second-order consensus protocol with normal positions as the coordination variables. In time coordination phase, based on the quasi-equilibrium gliding condition and the assumption of uniform deceleration motion, the analytical expression of time to go is derived. Then, the cooperative guidance method is developed using the first-order consensus protocol with time to go as the coordination variable. The proposed method takes full consideration of the characteristics of hypersonic gliding vehicle, such as complex nonlinear dynamics, no thrust, and quasi-equilibrium gliding condition, and no online numerical iteration is needed, which is well applicable for hypersonic gliding vehicles. Simulation results demonstrate the effectiveness of the formation control and cooperative guidance method.

Analysis of motor capacities in the maturational stages of female adolescents

Introduction: Maturation is a biological phenomenon inherent to the human being that acts alongside environmental factors in its relationship with the development of children and adolescents.Objective: To analyse the motor skills during maturational stages of female adolescents.Methods: This study included 133 female adolescents aged between 10 and 17 years from federal schools in the city of Rio Branco, State of Acre, Brazil. Sexual maturation was evaluated using Tanner’s self-assessment. Motor skills were assessed using the following tests: strength (Jump Test); coordination (Burpee Test); balance (Flamingo Test); flexibility (Sit and Reach Test); agility (Shuttle Run Test). The data were analysed using R software through analysis of variance. The significance level was fixed at 5%.Result: No significant statistical results were found for strength, agility, balance and flexibility, evidencing that maturational advances did not influence these skills. In the coordination variable, significant results were obtained.Conclusion: The results of this study suggest that maturational advancement in adolescents does not influence strength, agility, balance or flexibility. However, it does influence coordination, presenting better performance at stage P2.

Partition of the Optimality Problems in Mechatronics

In the paper two examples of division of the mathematical model for optimization are presented: a drive composed of an electric motor and mechanical transmissions, and an electromagnetic multi-coil linear drive. The first example shows that each step of the mechanical transmission may be optimized separately, if an overall power efficiency and a mass are taken as the optimality criteria for the whole drive, provided the adequate coordination variables are adopted, and these are ratios of the gears. In the other example it is demonstrated that the whole problem may be divided into three sub-problems, accordingly to the computing environment: ordinary differential equations are applied to model a mechanical part, and partial differential equations are modelling an electromagnetic field and a voltage distribution, with the moving core. The transient position of the core is the coordination variable. Finally, methodological suggestions on the systematic way of decomposing a design problem into sub-problems are proposed.
