DYNAMIC COMPENSATION FOR A ROTATIONAL MOTION SIMULATOR

摘要

A spacecraft attitude control simulation must be completed by a excitation source on its angular sensors to close and test its control loop. To provide this excitation, an angular motion simulator is necessary in the loop. However, this device has its own dynamical characteristics, which is unpredicted on the original control project and it can cause important changes in the control loop performance. In order to minimize those effects on the simulation loop, this work presents a proposition of a digital compensator design to cope with such undesirable dynamics, and a method to evaluate the obtained models.
