Abstract
A method of controlling pointing for a flexible structure such as a satellite includes: providing feedforward and reference inputs of a pointing control system with prefilters; and scheduling the prefilters and a bang-bang input to the pointing control system as a function of a desired input.
Claims24
A method of controlling pointing for a flexible structure, comprising:
- providing feedforward and reference inputs of a pointing control system with prefilters;
- and
- scheduling the prefilters and a bang-bang input to the pointing control system as a function of a desired input.
A method of controlling pointing for a flexible structure, comprising:
- providing a closed loop control system with feedforward and reference paths;
- and
- providing, to the feedforward and reference paths, inputs that have spectral content distributed over a closed loop bandwidth of the system.
A method of controlling pointing for a flexible structure, comprising:
- providing a closed loop control system to a flexible structure;
- and
- providing, to the closed loop control system, an acceleration command, R(t), which is a function of a maximum angular velocity ωM, a maximum angular acceleration αM, and a slew angle θ.
A method of controlling pointing for a flexible structure, comprising:
- providing a closed loop control system of a flexible structure;
- and
- providing, to the closed loop control system, a bang-bang acceleration input that takes into account uncertainty related to plant dynamics.
A method of controlling pointing for a flexible structure, comprising:
- providing a pointing controller designed to receive bang-bang inputs and to take uncertainty related to ignorance of plant dynamics into account.
A method of controlling pointing for a flexible satellite, comprising:
- providing a satellite pointing controller designed in consideration of modeling uncertainty.
