The computations of the high-order partial derivatives in a given problem are often cumbersome or not accurate. To combat such shortcomings, a new method for calculating exact high-order sensitivities using multicomplex numbers is presented. Inspired by the recent complex step method that is only valid for firstorder sensitivities, the new multicomplex(More)
The aim of this paper is to consider the modelling and control issues arising in the design of a station keeping system for geostationary satellites based on on-off electric thrusters. In particular, a model for the dynamics of a geostationary satellite affected by perturbations is derived and the electric station keeping problem is then formulated as an(More)
