A supervised stochastic learning method called the Gaussian Process Regression (GPR) is used to design an autonomous guidance law for low-thrust spacecraft. The problems considered are both of the time- and fuel-optimal regimes and a methodology base

The eigenstructure assignment scheme for robust multivariable state feedback control is extended to redundantly actuated dynamical systems. The fact that the plants that are atleast square allow for the exact assignment of an arbitrary orthonormal se

In this paper, a continuing research effort is detailed aimed at effecting practical hinge-less closed- loop flow control of wings. The systematic evolution of syntheticlpneumatic actuators suitable for this purpose, via distributed actuation, is des

A novel method is presented to carry out near-minimum-time maneuvers of a spacecraft of unknown inertia. The formulation assumes the presence of three orthogonal reaction wheels located near the system mass center and oriented arbitrarily with respec
