Abstract:
1. A control and regulation method for servo-controlling an inertial speed of rotation (ω i ) of a piece of equipment movable in rotation about an axis of rotation that is stationary relative to a structural frame of reference, the method comprising: setting a setpoint (ω using an internal regulation loop to amplify a difference (ω integrating the inertial speed of rotation (ω calculating cos β and sin β; calculating the integral (Is) of sin β and the integral (Ic) of cos β; identifying the coordinates (Xc, Yc) of a center of a circle defined by the values of the integrals (Ic) and (Is); applying a gain (k) to the coordinates (Xc, Yc) and calculating a correction term that is a function of the gain (k), the inertial angle of rotation (β), and the coordinates (Xc, Yc); and adding said correction term to the setpoint (ω
