Abstract
Ordinary gyroscopic stabilizer consists of appropriate gyroscope mounted in precession (inner gimbal) and stabilizer (outer gimbal) frames. The whole stabilizer is pivoted in base frame. In standard configuration, the air spring, damper and compensation motor are mounted between base frame and frame of stabilizer. This paper aims to analyze the possibility of simplification this standard configuration. The simplification consists of replacement of the compensation motor by active controlled air spring. Leaving out compensation motor brings minimal change to the whole system, because air spring control circuit and valve are already mounted and are used to adjust the initial position of the stabilizer frame. This solution does not increase the costs. Successful application of proposed modification could reduce the prize of the system. The issue is approached by analysis of nonlinear dynamical model of gyroscopic stabilizer with built-in air spring model, electro-pneumatic valve and correction and compensation system. Precise characteristics of applied air spring and control elements of analyzed system were measured in university laboratories.
