Abstract :
A method is proposed for generating on-off commands for rest-to-rest slewing of two-mode systems. When the on-off actuators are thruster jets, the command profiles can be designed to use any specified amount of fuel. A beneficial merit of the presented procedure is that the on-off commands are expressed by closed-form functions of the system parameters and desired maneuver. The command performances are evaluated with respect to slewing speed, maximum transient deflection, and robustness to system uncertainty. The performance measures are compared to those of bang-coast-bang commands. The proposed method is illustrated using a numerical simulation of a benchmark system with two flexible modes.
