The invention provides a stable platform servo control system, and aims to solve the technical problems that a traditional motor servo control system cannot meet the control precision requirement of the system, mechanical resonance is difficult to restrain, and the size and the weight are large. The stable platform servo control systemincludes a DC/DC, an azimuth motor arranged on an azimuth shaft, an azimuth fiber-optic gyroscope, an azimuth encoder arranged on an output shaft of the azimuth motor, an azimuth shaft control assembly, a pitching motor arranged on a pitching shaft, a pitching fiber-optic gyroscope, a pitching encoder arranged on an output shaft of the pitching motor, and a pitching shaft control assembly. The control assembly comprises an FPGA, a DSP, a three-phase bridge, a PWM drive circuit, a current acquisition circuit, an AD conversion circuit and a communication circuit. The DSP comprises a position loop controller, a speed loop controller, a current loop controller, a digital wave trap and a PWM generator, and is used for realizing an SVPWM control algorithm or an SPWM control algorithm and a current, speed and position three-closed-loop control algorithm of an azimuth axis.

    本发明提出一种稳定平台伺服控制系统,以解决传统的电机伺服控制系统不能满足系统的控制精度要求,机械谐振难以抑制,且存在体积和重量较大的技术问题。包括DC/DC、设置在方位轴上的方位电机、方位光纤陀螺、设置在方位电机输出轴上的方位编码器以及方位轴控制组件,以及设置在俯仰轴上的俯仰电机、俯仰光纤陀螺、设置在俯仰电机输出轴上的俯仰编码器以及俯仰轴控制组件;控制组件包括FPGA、DSP、三相桥、PWM驱动电路、电流采集电路、AD转换电路及通信电路;DSP包括位置环控制器、速度环控制器、电流环控制器、数字陷波器及PWM发生器,用于实现SVPWM控制算法或SPWM控制算法,以及方位轴的电流、速度和位置三闭环控制算法。
