Fractional Order systems

1. Research is not anymore confined to integer order systems anymore. Work is now going on in fractional order systems since fractional order systems are more relevant to real time systems!


2. Fractional order controllers especially tuning methods of Fractional Order Proportional Integral Derivative (FOPID) controllers are being designed.


3. Identification of linear systems through relay based auto tuning of fractional controllers is being pursued too.
