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 control of the aircraft attitude in a three-dimensional space is considered. The attitude is described by the Euler angles between the axes of the body-fixed coordinate system and the Earth frame. A method of calculating the torque driving the aircraft to a prescribed attitude is proposed.

Helicopter being highly coupled and complex nonlinear system is difficult not only from modeling perspective but also from control design. Hence, it must be ensured that designed control system will make helicopter flight safe and will improve efficiency of completing mission.

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.

A direct adaptive controller was developed for a class of interceptors. The control design architecture is based on a model reference adaptive control concept. The adaptive control algorithm is configured together with a traditional attitude control system (ACS) to provide robust performance. System uncertainties arising from inertial measurement noise,

ADAPTIVE CONTROL OF MISSILE ATTITUDE
IFAC Proceedings Volumes, 1987Abstract The attitude control of a missile should not only be able to make it follow predetermined Euler angles but also minimize the effects of wind gusts along its trajectory. Fixed gain controllers with good performance are impaired by the highly nonstationary nature of the missile dynamics.

CONTROLLING THE ATTITUDE of a satellite vehicle should be a simple job. The body behaves as if it were suspended on a frictionless pivot. Control torques can be small. There usually is no need for extreme precision in measurement. And adequate response times are ridiculously low by conventional servo standards.

A main system is provided with one or more subordinate systems pivotally connected thereto. The subordinate system can be programmed as desired to move in reference to the main system by the provision of a magnetic attraction acting upon the subordinate system to control the relative movement thereof against a resistance to movement such as may be ...

THE AGE OF SATELLITES is here. With it has come some interesting attitude control problems. For many uses, it is desirable to have a satellite oriented in a unique attitude with respect to the earth. If such a unique stable attitude exists, the attitude-control problem is reduced to a damping problem.
