Tuning of Pulse-Width Pulse-Frequency Modulator using PSO: An Engineering Approach to Spacecraft Attitude Controller Design
In this paper, a new technique for fine tuning of spacecraft autopilots based on pulse-width pulse-frequency (PWPF) modulators is presented. PWPF is one of the most commonly used approaches to control signal modulation. Its main application is found in spacecraft controllers to produce discontinuous on-off control signals for two situational actuators. The main reasons for the popularity of thi...
متن کاملPreliminary Design of Spacecraft Attitude Control with Pulse-Width Pulse-Frequency Modulator for Rest-to-Rest Maneuvers
In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...
متن کاملOn-off Attitude Control Using Pulse-width Pulse-frequency Modulated Input Shaper
Kinetic kill vehicle (KKV) is actuated by on-off thrusters to adjust its attitude, how to modulate continuous control commands to on-off or pulse signals to meet the requirements of the thrusters is a challenging task. Pulse-width pulse-frequency (PWPF) modulation is an effective method that provides pseudolinear operation for on-off thrusters. In this work, a new thruster configuration of the ...
متن کاملdesign of an analog fuzzy logic controller chip
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
15 صفحه اولPulse Width Modulation Applied to Olfactory Stimulation for Intensity Tuning
For most olfactometers described in the literature, adjusting olfactory stimulation intensity involves modifying the dilution of the odorant in a neutral solution (water, mineral, oil, etc.), the dilution of the odorant air in neutral airflow, or the surface of the odorant in contact with airflow. But, for most of these above-mentioned devices, manual intervention is necessary for adjusting con...
