本文提出了一种改进的PID控制器参数的双奈奎斯特点辨识自整定算法。通过改进的继电反馈实验，确定了Nyquist图上的临界点及其邻近点，并利用这些临界点推导出了PID控制器参数的确定公式。这些公式是由主极点近似和配置方法推导出来的。我们可以考虑以阻尼比（/spl zeta/）作为设计指标的过程的时域响应。
This paper deals with an advanced automatic tuning algorithm of the PID controller using two Nyquist points identification. The critical point on the Nyquist plot and its neighboring point are identified from the modified relay feedback experiment and used to make the formulas to determine the parameters of the PID controller. The formulas are derived from the dominant poles approximation and placement method. We can consider the time domain response of the process with damping ratio (/spl zeta/) as a design specification.
