Damping the pulsation moments of the engine of power stabilization by the combined method of H <sub>2</sub>/H <sub>∞</sub> control
The subject of study is a problem of synthesis of a dynamic controller for controlling the positional stabilization of a single-axis gyrostabilizer, in conditions of the uncertain external disturbing factors (the pulsation torque of the engine of power stabilization) and at the presence of the measurement noise. The stabilization refers to astatic controlled achieving of the stabilized state and minimizing the influence of the external disturbances and measurement noise on the quality of the transition process. To suppress the unknown external disturbances, that have the finite quantity of energy, the authors use the H <sub>∞</sub> optimization, while the concept of mixed H <sub>2</sub>H <sub>∞</sub> control is applied for controlling at the presence of the noises in the measurement channels.
