According to the invention, the cycle running time of the program is short, the running speed is high, and a complicated logic operation can be performed; the dual-motor synchronous control system is realized, and the response speed and control precision are higher; and the control method can effectively eliminate the gear gap and achieve the purpose of precise positioning without affecting the dual-motor synchronization.

Description

technical field [0001] The invention relates to the field of mechanical control, in particular to a dual-motor servo control system and a control method thereof. Background technique [0002] The radar servo system is an electronic device that controls the position of the radar and various motion parameters, and is a typical electromechanical automation control technology. [0003] The azimuth transmission system of the radar servo turntable is an important part of the radar turntable. Its function is to drive the radar antenna for high-speed, high-precision direction positioning, and can automatically rotate the antenna to capture and track targets, so it is also called a servo system. The radar control system consists of a mechanical transmission part and a servo control part, which can realize the forward rotation, reverse rotation, tracking and stop of the radar antenna. [0004] The servo system needs to obtain the position information of the antenna in real time. The ...
