Abstract :
This paper deals with stability problem of inverted pendulum controlled by a fractional order PD controller. D-decomposition method for determining stability region in controller parameters space is hereby presented. The D-decomposition problem for linear systems is extended for linear fractional systems and for the case of nonlinear parameters dependence. Some comparisons of fractional and integer order PID controllers are given based on simulation results.
