Adaptive Control Combined with Integral Concurrent Learning for Trajectory Tracking Near Asteroids
… parameter estimation with adaptive control. An Integral Concurrent Learning (ICL) framework is used to estimate a reduced set of gravity expansion coefficients that represent the dominant perturbing effects of the asteroid’s irregular shape. These estimated coefficients are then fed into a Model …

Solar Sailing Adaptive Control Using Integral Concurrent Learning for Solar Flux Estimation
… A Lyapunov-based control law along with integral concurrent learning is suggested to accomplish and prove global exponential tracking of the estimated parameters and states of interest, without satisfying the common persistence of excitation condition, which in most nonlinear systems …

Adaptive Control for Spacecraft with Flexible Appendages with Unknown Parameters
… parameters of the system are estimated with Integral Concurrent Learning (ICL) and a detailed framework for implementing this architecture onboard using real hardware is presented and validated with experimental results obtained from a real testbed. The outcome of this investigation will …

Online Estimation of Unknown Parameters for Flexible Spacecraft
… spacecraft is maneuvered. The controller uses integral concurrent learning (ICL), an adaptive scheme that records inputs and outputs provided by sensors mounted on the flexible body. The novelty of this investigation is the development of self-adapting control gains for both the tracking error …

Solar Sailing Adaptive Control Around the Earth-Moon Lagrange Point L4 for Stellar Observations
… an adaptive control architecture, using integral concurrent learning, is proposed to account for fluctuations in the solar flux and degradation of the sail surface for long-term tracking to the nominal trajectory, enabling repeated observations of the solar corona within the Moon's umbra …
