AI Technical Summary
Existing electric servo systems have poor anti-interference capabilities in systems that include brushless DC motors, reduction gears, and ball screws, and their control performance cannot be preset, which affects the missile flight control effect.
By calculating the output tracking error based on the desired and actual output angles of the electric servo motor, a dynamic surface model is established for adaptive anti-interference control. Unknown parameters are estimated using error transformation and adaptive law, and virtual control signals and filter outputs are designed to achieve adaptive adjustment of the electric servo motor control voltage.
It achieves specified performance tracking control of the output angle of the electric servo motor, improves anti-interference capability and control accuracy, and is suitable for electric servo motor systems that include brushless DC motors, reduction gears and ball screws, achieving the requirements of high precision and fast response.
