Abstract

Abstract

In order to achieve beam scanning of mechanical phased array antenna, the brushed DC motor (BDCM) is adopted to drive a helical antenna element to rotate to a predetermined radiation phase. The paper uses the digital signal processor (DSP) TMS320F2812 to implement the position control system of BDCM, and describes the hardware design, control strategy and software design of the control system. In order to achieve fast and no overshoot response, the fuzzy proportional integral derivative(PID) control algorithm is researched and applied to the control system. Experiment results indicate that the position control system of BDCM is simple, and has good control performance, which can meet the requirements of fast and accurate phase control of the helical antenna element.
