The article shows the principle possibility of achieving precision control of the electric drive of the optical fiber winding mechanism of the sensory elements of avionics. A two-channel regulator is proposed for precise control of the linear velocity and traction force of the electric drive of the optical fiber winding mechanism of the avionics sensory elements. The precision of the operation of proposed controller compared to the prototype is confirmed by a reduction of more than an order of magnitude of the impact of pulsed episodic disturbances and almost two orders of magnitude of the impact of continuous stochastic disturbances on the linear velocity of the optical fiber and the traction force on it, which creates the electric drive of the optical fiber winding mechanism of the avionics sensory elements. The essence of proposals for precision control lies in the structural and algorithmic improvement of the prototype system. In the optical fiber linear velocity control channel, it is proposed to use the PID controller existing in the prototype system. In the channel for controlling the traction force acting on the optical fiber, it is proposed to use the GID - regulator.
