Reply To: Fractional PID Controller Design

[Naeem Haider]

Hi,

i am making a simulink model of a Ball and beam system with PID controller and i have used transfer function of ball and beam and servo motor to design a pid controller….

and now i want to use Fractional PID with the same model… and when i put fractional pid block in the simulation it gives an error of LTI ??? system.. so i used State space models instead of transfer function …. but its not working ….. please tell guide me what to do and how to model ball and beam system with FOPID in simulink …. ..
