This paper investigates the potential of fuzzy pulse width pulse frequency controller (FPWPFC) for a 3-axis thruster attitude control on low earth orbit satellites. The control objective is to point the satellite to the desired state within a minimum of time and with a minimum fuel consumption. A comparative study of the FPWPFC, the proportional derivative pulse width pulse frequency controller (PDPWPFC) and the proportional derivative bang-bang controller (PDBBC) with dead zone controller is performed to evaluate the performance of the attitude control system during a 3-axis attitude control. The robustness of FPWPFC has been validated using the Monte–Carlo method. Simulation results demonstrated the effectiveness and advantages of the proposed controller to minimize the fuel consumption.
