Design of Digit Stabilized Platform Control System Based on STM32 Microcontroler

针对数字稳定平台的隔离度指标要求,设计了一个以STM32微控制器为核心器件的稳定平台数字控制系统。分析了稳定平台控制系统的工作原理,对硬件和软件系统进行了详细说明,使用数字滤波和双闭环PID算法对数字信号进行处理,然后输出脉宽调制信号控制直流电机。实测结果表明该稳定平台系统能够有效的隔离扰动。

In view of the requirements of isolation for a digit stabilized platform, the digit stabilized platform control system based on STM32 microcontroler is designed. The working principle of stabilized platform control system is analysed. The hardware and software system are described in detail. Then process the digital signal with the digital filtering algorithm and PID algorithm and use the pulse width modulation(PWM) signal to control the DC motors. The testing result show that the stabilized platform system can isolate the disturbances effectively.
