摘要：
We propose a method of constructing a stabilization system for the camera optical axis using PI controllers and cascaded observers of estimate of the reduced disturbances caused by external and parametric disturbances. The obtained disturbance estimates are used in the control law of brushless direct current motors to increase the stabilization accuracy of the absolute angular velocity of the camera optical axis. The simulation results confirm the effectiveness of the proposed stabilization system. © 2019, Allerton Press, Inc.
