Unmanned aerial vehicles are used to observe objects from the air in both kind of users – military and civilian. During the flight, UAV constantly is changing its orientation. This is due to weather conditions and commands coming from the ground control station. It has directly influence to the quality of the video stream transmitted from the cameras to the GCS. That disturbed image is hard to effective analyse. In order to eliminate the interference, UAVs are equipped with stabilized gimbals. The most of gimbals designed in Air Force Institute of Technology are using BLDC motors. Some of these systems use encoders for determining the absolute angle of motor rotation. The smaller one, which is up to 200 g, is not provided with these sensors. This angle is calculated without any feedback from the system. It is calculated by the BLDC motor`s control signals. However, lack of feedback can provide unstable work of gimbal, if it will be pushed by any force from environment. During the flight, it is unacceptable to head optoelectronic stopped working steadily. Therefore, there is a need to develop algorithms for securing the proper operation of the system stability. These algorithms can be used in other systems using stepper or BLDC motors.
