AI Technical Summary
Existing dual-axis gimbal control systems are prone to response delays, decreased stability and accuracy, and steering jamming when the load weight changes. In traditional structures, there is a large amount of inter-axis interference, making it difficult to achieve high precision and fast response.
The dual-axis gimbal control system, which combines feedforward control with cascaded fuzzy PID control, uses a servo motor drive and harmonic reducer in conjunction with a worm gear structure and a limit structure to achieve precise clamping and angle adjustment of the camera or sensor. The feedforward control and cascaded fuzzy PID control provide timely feedback on the equipment status, improving adjustment accuracy and response speed.
It achieves high-precision adjustment and fast response of dual-axis gimbal, improves the response delay and stability problems in traditional structures, and enhances the attitude stability and flexible orientation capability of the equipment.
