Nonlinear PID and Sliding Mode Control applied to a New Generation of Micro-Pump for Small Satellites

The aim of this paper is to emphasize the studies carried out for the new generation hydrazine pump system in term of nonlinear control in order to simplify the existing controllers that have been designed for this system. It consists of a classical PID structure based on a nonlinear feedback function which allows having a simple control input on the device. Our purpose is thus to implement a relatively simple controller on the new hydrazine pump to make it reliable and cost-effective.
