具有良好动态响应特性的Boost变流器控制

提出用于Ｂｏｏｓｔ变流器的一种新的控制方法，该法根据输出电压偏离给定值的程度，使系统的控制方法在电流反馈控制方式与全状态变量反馈控制方式之间自动切换，从而降低了系统稳定性要求对选择反馈系数的严格限制。本文还给出了计算量较少的前馈控制算法，前馈控制可提高系统的抗干扰能力。计算机仿真结果表明，该控制方法的效果是较明显的。

A New Control Method for Boost Converted with the Characteristics of Well-Behaved Dynamic Response

A new control method for boost converter which realizes the automatic interswitching between the current feedback control model and the whole state variable feedback control model acconding to the deviation of output voltage from the nominal value is presented in this paper. An algorithm for the feed-forward control which takes only less computation and improves the imunity of the converter is also given in this paper. Finally, the figures yielding from the computer simulation show that the effect of this new control method is prominent.
