摘要：本文介绍了DC/DC变换器数字PID控制方法，对增量式和位置式数字PID控制算法进行比较研究。以DC/DC变换器为控制对象，根据硬件条件确定采样周期，运用极点配置方法整定比例、积分、微分系数，通过MATLAB仿真对整定参数进行修订，最后采用抗积分饱和PID算法完成系统控制。实验结果证明：所整定的参数能使系统运行平稳，满足系统所要求的静、动态特性。

Abstract：The paper introduces the digital PID control method for DC/DC converter, analyzing the incremental and located method of digital PID control algorithm by comparison. According to the hardware that DC/DC converter was used as the control object, the sampling period was determined, PID proportional, integral, differential coefficients by pole configuration was set, the parameters through the MATLAB simulation were amended. Then the anti-integration saturation PID controlled the system. Experimental results proved that DC/DC converter worked stably by revised parameters. The system was with excellent static and dynamic characteristics.
