ELECTROMAGNETIC PROCESS FOR CONTROLLING ORIENTATION OF A PLATFORM AND PLATFORM FOR CARRYING OUT SAID PROCESS

摘要

Electromagnetic method to accurately control the orientation of a platform according to two axes wherein pivoting of the platform about two orthogonal axes passing through its centre is effected by electromagnetic means, with the servo-control being obtained by using a detector responsive to the angle of deviation from a reference direction, an amplifier, a low-pass filter, a phase lead filter and power amplifiers supplying currents to the electromagnetic devices. The method is particularly adapted to the orientation of platforms carrying means such as aerials or inertia wheels intended for piloting a space vehicle.
