Application of Fractional-Order Control on Real-Time Targets

Abstract

The chapter presents a case study regarding the tuning, implementation and experimental results of a fractional-order PI controller for a velocity system. The case study is a modular servo system, which is briefly described at the beginning of the chapter. The experimental results indicate the accuracy, efficiency and robustness of the tuned fractional-order controller which outperforms the classical control algorithm. The implementation aspects for general fractional-order controllers are described next, including analog and digital approximation methods. The chapter also discusses pitfalls on the actual implementation of fractional-order controllers on dedicated real-time devices.
