介绍了一种数字PID控制在能谱稳峰方面的应用。该稳峰技术将满足需求的目标峰值作为系统的参考峰值,根据系统运行过程中实测峰值与参考峰值的偏差结合数字PID算法调节可编程增益放大器来稳峰,是一种结合硬件与软件的稳峰技术。实验结果证明,这种能谱稳峰技术具有稳峰速度快,稳定性好,抗干扰能力强等优点。

In this paperthe application of a digital PID control in the spectrum stabilization is introduced. The energy spectrum peak stabilization technique combines hardware and software technologyit sets the target peak values which meet the requirements as system reference peak valuesputting the deviation between the measured peak value and the reference peak in the running process of the system and digital PID algorithm together to adjust programmable gain amplifier to stabilize the peak. The experimental results show that the energy spectrum peak stabilization technique has the advantages of stabl...
