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.
Keyword:DC/DC Converter, Digital PID, Pole configuration
