Problems solved by technology
[0003] The current rudder servo system mostly adopts DC motor control, its control method is relatively simple and the control theory is relatively mature, and it also has a good control effect, but in many rudder servo fields with special application requirements, such as precision guided weapons, micro rudder systems, etc., This type of motor often cannot meet the requirements of the rudder servo system due to its inherent shortcomings such as poor low-speed performance and weak anti-electromagnetic interference ability. The inherent defects of the DC motor rudder servo system are difficult to be effectively solved
