Routing strategies for underwater gliders
rapidly reach a specified waypoint or to maximize the ability to map a measured field, both in the presence of significant currents. For rapid transit in a frozen velocity field, direct minimization of travel time provides a trajectory ‘‘ray’’ equation. A simpler routing algorithm that requires less information is also discussed. Two approaches are developed to maximize the mapping ability, as ...
متن کاملParticle Filtering for Sequential Spacecraft Attitude Estimation
A new spacecraft attitude estimation approach using particle filtering is derived. Based on sequential Monte Carlo simulation, the particle filter approximately represents the probability distribution of the state vector with random samples. The filter formulation is based on the star camera measurements using a gyro-based or attitude dynamics-based model for attitude propagation. Modified Rodr...
متن کاملUnscented Filtering for Spacecraft Attitude Estimation
A new spacecraft attitude estimation approach based on the Unscented Filter is derived. For nonlinear systems the Unscented Filter uses a carefully selected set of sample points to more accurately map the probability distribution than the linearization of the standard Extended Kalman Filter, leading to faster convergence from inaccurate initial conditions in attitude estimation problems. The fi...
متن کاملCombining of Differential Evolution and Implicit Filtering Algorithm Applied to Electromagnetic Design Optimization
Differential evolution (DE) is a population-based and stochastic search algorithm of evolutionary computation that offers three major advantages: it finds the global minimum regardless of the initial parameter values, it involves fast convergence, and it uses few control parameters. This work presents a global optimization algorithm based on DE approaches combined with local search using the im...
متن کاملStabilization and Coordination of Underwater Gliders
An underwater glider is a buoyancy-driven, fixedwing underwater vehicle that redistributes internal mass to control attitude. We examine the dynamics of a glider restricted to the vertical plane and derive a feedback law that stabilizes steady glide paths. The control law is physically motivated and with the appropriate choice of output can be interpreted as providing input-output feedback line...
