Abstract
Control moment gyroscopes (CMGs) are used as actuators in some applications like satellites and spacecrafts attitude control, and stabilization. A good system model is fundamental for control applications. This paper presents a detailed modeling process of a four degrees of freedom (DOF) CMG unit, which kinematics stage is based on a defined convention using quaternion algebra, and dynamics stage is based on Gibbs-Appell equations in Kane’s proposed dynamical equations form. Two tests that analyze the main characteristics of the plant are considered in order to validate the generated nonlinear model, which numerical simulations results are compared to the practical experiments.
