| Summary: | 碩士 === 國立雲林科技大學 === 電機工程技術研究所 === 87 === An approach for PID parameter tuning of multivariable (multi-input or multi-output) systems is proposed in this thesis. The proposed method is developed based on the Taguchi method, which has been used widely in quality engineering, and the tuning process is performed experimentally. In this manner, one does not need to determine the mathematical model of the controlled plant, which is usually hard to obtain in practice. Moreover, since the number of experiments needed in the tuning process is finite, the proposed method will be efficient in time in comparison with other tuning techniques. In the simulation examples, several SISO (single-input and single-output) systems and a multivariable seesaw system are used for illustration. The simulation results will verify the validity and the feasibility of the proposed method.
