Input force reconstruction using wavelets with applications to a pulsed plasma thruster

The problem addressed in this paper is the determination of the performance of a pulsed plasma thruster used in control of microsatellites. In particular, the estimation of the impulse bit from data recorded in a test stand based on the resonant blade principle. An new approach to the problem is introduced. It is based on wavelets, in a multiresolution framework. The results obtained are shown. This method improves the performance of the previously used.
