Time-Optimal Low-Thrust Formation Maneuvering Using a Hybrid Linear/ Nonlinear Controller

摘要

A hybrid linearonlinear controller was formulated that combines the efficacies of linear control and time-optimal bang-bang control methodologies to efficiently maneuver spacecraft in formation. The system equations are formulated based on the time-averaged values of the relative coordinates rather than their instantaneous values. This formulation is very appropriate for low-thrust fuel-optimal problems in which unwanted fuel actuation on cyclic disturbances is to be minimized.
