摘要
根据燃料电池电站功率逆变系统非线性的特点,进行线性化处理,采用数字化PI控制其输出波形。采用带滤波电感电流内环的电压瞬时值控制策略,电压瞬时值外环反馈控制提高系统动态响应,电流瞬时值内环反馈控制提高系统稳态输出精度,选用TI控制器软件平台试凑PI参数。实验表明,该设计方案快捷、有效,电压输出波形良好。
According to the character non-linear of the fuel cell power plant inverter system,the linear treatment is taken and digital PI control of the output waveform is proposed.The voltage instantaneous feedback control strategy with filter inductor current inside loop is used to improve dynamic-state response and steady precision separately.The PI parameters are designed by trial and assemble method with TI controller software platform together.The experiments show that the design is effective,and efficient,and the voltage output waveform is good.
