摘要：
This paper discusses the inaccuracies involved in applying the describing function to obtaining plant information from autotuning measurements. Simple algorithms are given to improve the results for first order plus time delay plants (FOPTD). Attention is also drawn to the large errors which can occur when using autotuning for an unstable FOPTD plant.
