提出一种基于前馈控制的棒位探测器励磁电源设计方案,该方案采用高频开关整流逆变电路设计,在传统比例积分(PI)控制的基础之上加入了前馈控制,用以抑制可测不可控的干扰因素对控制对象的影响,并通过理论分析与仿真试验,验证了本文提出的设计方案在保证控制响应时间的同时降低了输出纹波,提高了电流幅值精度。

This paper presents a design scheme of rod position detector excitation power based on feedforward control. High-frequency switching AC-DC-AC inverter circuit is used in this scheme, and the feedforward control is added on the traditional Proportional-Integral(PI) control to suppress the influence of measurable and uncontrollable factors on the controlled object. Through theoretical analysis and simulation test, the design scheme proposed in this paper is verified, and it can reduce the output ripple, and improve the current amplitude accuracy while ensuring the corresponding control time.
