The Design of Servo System for Azimuth of Directional Antenna Based on PMSM

directional antenna is widely used in the measurement and control for Short range UAV because of its high gain in the range of beam angle, the speed of UAV is very fast, so the requirements for speed and acceleration of directional antenna is very high, step motors are usually in the traditional directional antenna systems, which works in the open loop and has low positioning accuracy, slow speed response and dynamic regulation, In order to meet the requirements of the directional antenna servo system, the design of servo control system for Azimuth of directional antenna based on PMSM and CAN bus communication is introduced in this paper . The test results indicate that the dynamic response of antenna servo system is very quick and tracking accuracy is very high. which can be well applied in the target tracking system.
