[0082] A control method based on a BP neural network combined with an active disturbance rejection controller for a three-axis pan-tilt servo motor, the method ignores the armature inductance of the three-axis pan-tilt servo system containing a friction model, and the three-axis The current loop and speed loop of the pan / tilt servo system are both open loops, the position loop is closed loop, and the entire three-axis pan / tilt servo system with friction model is a closed-loop feedback system. The friction link is regarded as a part of the total disturbance of the servo system. The extended observer in the anti-disturbance controller estimates and compensates the friction torque in real time, and the three parameters of the extended state observer in the active disturbance rejection controller of the three-axis pan-tilt servo system with friction model are analyzed by using BP neural network beta 01 , β 02 , β 03 and the two parameters β of the nonlinear state error feedback ...
