| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 96 === PID controllers are often used in the industry, due to its simple structure. But how to determine PID controller parameters for better system performance is studied for many decades .In the industry, it always used the operator’s experience to set the PID controller parameters. In this thesis, a new algorithm is proposed for PID controller parameters tuning. This algorithm is based on the Iterative Feedback Tuning (IFT) method and two sets of PID controller parameters are tuned iteratively, it correspond to the transient response and steady-state response. First, tune the transient PID controller parameters to find the better parameters. When transient PID controller parameters have tuned, then tune the steady-state PID controller parameters. This proposed algorithm results show performance better than other classic tuning methods and the IFT method.
