Synchronization and Control of Attitude for Spacecrafts:
The topic of this paper is to control and synchronize sphere-shaped spacecrafts in a leader-follower synchronization scheme. In order to achieve this objective, a nonlinear mathematical model of the vehicles has been developed. The design is based on rigid body dynamics where the vessel is actuated by means of three orthogonally mounted reaction wheels. The attitude dynamics is derived using Eu...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولFirst Signal in Space Analysis of GLONASS K-1
Russia’s global navigation satellite system starts the upgrade to a new level. The first GLONASS space vehicle with a CDMA coded signal was launched in February 2011. The article gives a short overview about all transmitted GLONASS-K1 signals. The main focus of this article is the new GLONASS CDMA signal L3. The signal quality is assessed by analysing the purity and symmetry of the spectrum. Th...
متن کاملDecentralized Adaptive Control of Large-Scale Non-affine Nonlinear Time-Delay Systems Using Neural Networks
In this paper, a decentralized adaptive neural controller is proposed for a class of large-scale nonlinear systems with unknown nonlinear, non-affine subsystems and unknown nonlinear time-delay interconnections. The stability of the closed loop system is guaranteed through Lyapunov-Krasovskii stability analysis. Simulation results are provided to show the effectiveness of the proposed approache...
