摘要：

A trial-and-error method that is a variation of Ziegler-Nichols tuning has been employed in the past for field tuning of PID controllers. This method is now extended for tuning of multiloop PI controllers. The Nyquist array method is refined to determine ultimate gains for multiloop tuning. The proposed method is simple to use and simulation results show that it avoids sluggish responses and unbalanced responses between loops that occur with other tuning methods such as BLT and sequential autotuning.
