Abstract
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.
