Model predictive control for rendezvous hovering phases based on a novel description of constrained trajectories
نویسندگان
چکیده
The present article proposes a predictive control law for orbital spacecraft rendezvous hovering phases. An innovative description of periodic spacerestricted trajectories based on computing the envelope of a family of curves is given. This description is used to provide a model predictive controller able to minimize the fuel consumption and account convex constraints, such as periodicity, saturation of the thrusters and space restrictions. The efficiency of this control algorithm is assessed on a board simulating the performance of devices usually employed in space applications. Keywords—FPGA embedded control law; Model predictive and optimization-based control; Convex optimization; Guidance, navigation and control of vehicles; Aerospace
