An Adaptive Approach for Impulsive Formation Maintenance Relevant to Distributed SAR Missions

چکیده
This paper proposes an approach for impulsive formation maintenance tailored to distributed synthetic aperture radar, i.e., a spaceborne system composed by several antennas working together provide enhanced remote sensing capabilities. The analyzed configuration is designed guarantee the presence of safety tube surrounding each satellite as dynamics evolve. Formation requirements are related general constraints on acceptable along-track and radial/cross-track separations. introduces adaptive logic which fulfills these constraints. Specifically, adaptively redesigned around chief every time geometry violated means procedure developed authors in previous works based relative orbit parameters. Once parameters defined, optimal burns required transfer computed using state-of-the-art approaches. Performance terms delta-v maneuver frequency two-spacecraft exploiting simulation environment MATLAB GMAT. In ideal conditions, it shown that costs limited, while close proximity requires fine sensitivity applied impulses. A first assessment impact navigation maneuvering execution errors indicates they play important role defining overall control effort.

Distributed Fuzzy Adaptive Sliding Mode Formation for Nonlinear Multi-quadrotor Systems
This paper suggests a decentralized adaptive sliding mode formation procedure for affine nonlinear multi-quadrotor under a fixed directed topology wherever the followers are conquered by dynamical uncertainties. Compared with the previous studies which primarily concentrated on linear single-input single-output (SISO) agents or nonlinear agents with constant control gain, the proposed method is...

15 صفحه اولA Bayesian approach to an adaptive preventive maintenance model
In this paper we consider a Bayesian theoretic approach to determine an optimal adaptive preventive maintenance policy with minimal repair. By incorporating minimal repair, maintenance and replacement, the mathematical formulas of the expected cost per unit time are obtained. When the failure density is Weibull with uncertain parameters, a Bayesian approach is established to formally express an...

This work was proposed as a Doctoral Thesis of Applied Computing Course at Brazilian National Institute for Space Research (INPE) and is a ongoing work. The main purpose of SICSDA is to allow that satellites control can be done through the same set of machines, enabling the choice of which one of the satellites is desirable to be monitored in a determined piece of time. Another important fact i...
