Abstract :
According to the idea of system identification, two degree of freedom PID based on desired dynamic equation (DDE-PID) has been improved. In this paper, DDE-PID has been applied in fractional order systems (FOS). According to results of simulations, the tuning based on this method needs only the step response of the plant. It is easy to perform. Meanwhile, it is convenient to adjust according to the physical meaning of parameters and have good effect on FOS.
