碩士 === 國立臺灣大學 === 機械工程學研究所 === 98 === The theory of fractional calculus has been established for over 300 years. However, the algorithm of fractional calculus was developed in the last 40 years. In this thesis, the fractional-order controllers are designed according to the characteristics of fractional-order systems in continuous time. Then, the stability and robustness of these controllers are discussed. The fractional-order controllers are achieved by direct and indirect discretizations and different algorithms. The research focuses in an application of fractional-order controllers for an infrared zoom lens servo. The implementation of the controllers is accomplished with a microprocessor PIC, which is used to switch the infrared zoom lens. Finally, the performance of fractional-order controller is shown in the experiment results.
