【摘要】 通过对以输出电压为控制对象和以输出电流为控制对象的电压控制型开关调节系统的两种不同的控制方式建立传递函数,对比分析了将控制对象从输出电压转变成输出电流后,随着控制对象的改变,系统带宽的下降是由于电流控制方式引入系数K造成的,从而提出了相应的改善方法,通过详细的理论分析、S im plis仿真和样机实验,验证了此方法是行之有效的,解决了工程中将控制对象从输出电压转变成输出电流后的困扰,具有较强的实践应用意义。更多还原

【Abstract】 The transfer function was built based on two different control methods of voltage-control switching modulation system taking output voltage and output current as control objects. With the change of control object from voltage control to current control, the decline of the bandwidth was caused by the introduction of coefficient K. the corresponding improving methods was proposed. By detailed theoretical analysis, Simplis simulation and prototype tests, the method was proved feasible, which solved the problem of changing control object from output voltage to output current with practical application value.更多还原
