What is it about?
This paper deals with the problem of spacecraft time-optimal reorientation maneuvers under boundaries and path constraints. The minimum time solution with keep-out constraints is proposed using the particle swarm optimization technique. A novel method based on the evolution of the kinematics and the successive obtainment of the control law is presented and named as inverse dynamics particle swarm optimization. It is established that the computation of the minimum time maneuver with the proposed technique leads to near-optimal solutions, which fully satisfy all the boundaries and path constraints.

Why is it important?
This work presents for the first time the Inverse-Dynamics Particle Swarm Optimization (IPSO), a numerical technique to give numerical approximate solution to optimal control problems. Improvements of IPSO are reported in following publications.
Perspectives
The technique presented in this paper is expected to give important results compared to other commonly used numerical techniques in the optimal control field. By means of future improvements, IPSO is expected to become a reliable technique for future investigation of optimal control problems.
