Synthesizing Relay-Based Spacecraft Attitude Control and Stabilization Ensuring High Quality without Velocity Sensors

The article deals with a relay-based system of attitude control and stabilisation with incomplete information on the state of the object under control. The control loop features no angular velocity sensors and uses internal feedback including the relay controller. We present the alignment diagram method and its capacity for efficiently solving engineering problems in analysing and synthesising control for systems of the class under consideration
