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.2383076 bytesapplication/pdfen-US分數階PID控制器紅外線變焦鏡組雙視野絕對定位fractional PID controllerinfrared zoom lensdual field-of-viewabsolute alignmentthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/256260/1/ntu-99-R97522808-1.pdf
