Abstract

In this paper, we use generalized incremental predictive control (GIPC) to stabilize attitude of satellite. We compare Generalized Predictive Control (GPC) with GIPC algorithm and present that GIPC has better performance. The three axis attitude control systems are activated in pulse mode. Consequently, a modulation of the torque command is compelling in order to avoid high non-linear control action. This work considers the Pulse-Width Pulse-Frequency modulator (PWPF) is composed of a Schmitt trigger, a first order filter, and a feedback loop. PWPF modulator has several advantages over classical bang-bang controllers such as close to linear operation, high accuracy, and reduced propellant consumption.
