Attitude control of a satellite using fuzzy controllers
Expert Systems with Applications, 2009This paper proposes the design of fuzzy controllers for the attitude stabilization of the Republic of China Satellite (ROCSAT-1). In the first step, the original satellite controllers, two classical linearized controllers, are superseded by two fuzzy controllers. The objective is to obtain faster convergent time and lower steady-state error.

Adaptive neuro-control for spacecraft attitude control
Neurocomputing, 1995Abstract Spacecraft attitude control is approached as a nonlinear adaptive control problem and neuro-control, which combines concepts from artificial neural networks and adaptive control, is investigated as an alternative to linear control approaches.

Spacecraft attitude control has a variety of requirements, which are mainly for attitude stabilization control and attitude maneuver control. Attitude stabilization control keeps the attitude of a spacecraft along a reference frame by overcoming the influence of the internal and external disturbance torque.

Attitude control of a helicopter
2012 International Conference on Computer Science and Information Processing (CSIP), 2012Helicopter dynamics system is a strongly coupled multi-variable nonlinear system, and the actual maneuvers in the presence of many uncertain factors. Therefore, in the design of helicopter flight controller, in order to ensure the safety of helicopter flight, improve the efficiency of completing the mission and reduce driver's work burden, it is not ...

A Nonlinear Feedback Control Law for Attitude Control
1986Nonlinear feedback control laws are proposed for large angle attitude maneuvers of a rigid satellite by using pulsed thrusters and reaction wheels. The kinematic equations in the quaternions parametrization together with the Euler dynamical equations constitute the mathematical model of the system under study.

Spacecraft pointing control is an essential technology for all robotic and manned spacecraft. A control system consists of sensing, actuation, and the dynamics of the spacecraft itself. Spacecraft control systems are of many types, but in this chapter, we will be concerned only with three axis pointing. We will use reaction wheels for actuation.

THE PROBLEM of attitude control exists to a certain extent with all kinds of vehicles, missiles, and projectiles. Attitude control is necessary or desirable for at least the following reasons: 1. To provide mental and physical comfort for passengers. 2. To provide proper environment and positioning to allow instrumentation to function. 3.
