Influence of pass band on triaxial hyrostabiliser stability. Circular criterion of stability

The influence of monoaxial channel bandwidth on the stability of triaxial hyrostabiliser is considered. Their interconnection is based on the dependence between control functions of unloading motor and the gyro relative precession angle. The circular stability criterion is proposed as a function of parameter defining the interconnection rate of stabilization channels; the criterion permits to demonstrate clearly the influence of pass band on the triaxial hyrostabiliser stability.
