<h2>A FEEDBACK CONTROL LAW FOR STATIONKEEPING WITH ON-OFF THRUSTERS </h2>
<h4> C.A. Kluever, G.S. Tanck - University of Missouri-Columbia </h4>
<h2> Abstract </h2>
A feedback control system for autonomous stationkeeping is presented. The control law is developed for a set of electric propulsion thrusters that operate in an on-off mode with constant thrust magnitude. The control law is derived by utilizing the discrete version of the linear Clohessy-Wiltshire equations of motion and the discrete-time asymptotic linear quadratic regulator (LQR) approach. The result is a flexible and reliable control scheme that can be tuned to provide a desired system response. Several stationkeeping maneuvers with this control law are presented.
