Fractional order self-tuning control

This paper presents an innovative design method of polynomial control laws by mean of pole placement which are actually smart solutions to many industrial applications. Even if this category of controllers is very popular in industry, most of their applications concern problems of constant reference signals. In this paper, we propose an indirect adaptive controller by fractional order pole placement, and show using a simulation example where this real time fractional order control strategy is applied to an air-lubricated capstan drive for precision positioning the improvement in system´s behavior when compared to the classical control scheme with integer order poles.
