Research on Drive Control Method of Scanning Mechanism of Radar Scatterometer Antenna

Abstract:

A set of drive control system has been developed for the scanning drive system of radar scatterometer antenna, according to the requirements of its scanning motion for speed stability with three-phase AC permanent-magnet synchronous motor(PMSM) driven by sine wave current as the execute component. The system can achieve the aim of controlling motion trace. The system composition, matching design of characteristic parameters such as speed and torque as well as control realization method, are described in this paper and the testing of main system performances such as speed stability is also briefly introduced. It is shown from the simulation and test that the designed system can complete the control of motion track with speed ability of up to 0.5% and can satisfy the given index requirements.
