Abstract:Aiming at the problems of long closed loop period and large volume in the traditional drive control scheme of photoelectric platform, this paper proposes a drive control method based on ZYNQ platform. By adopting the modular design idea and fully exerting the parallel processing advantage of the PL part in ZYNQ, the IP cores corresponding to the CLARK transform, PARK transform, PI control of quadrature axis and direct axis, inverse PARK transform and SVPWM module respectively are established. PWM signals are finally output to control the on-off state of the six drive arms. The PWM period of the system can reach 18 kHz, and the closed-loop period of the current loop can be limited within 50 μs, which greatly reduces the closed-loop time. The experimental results show that the response current of the quadrature axis can quickly follow the square wave and sine wave command signals, the three-phase current of the motor is smooth without distortion, and the ripple is small. The sinusoidal inputs with different frequencies are given to verify that the closed-loop broadband is higher than 318 Hz, which validates the effectiveness of the proposed drive control method in the paper. It has important reference value for realizing miniaturization and high-performance drive control.
