Efficient Fractional Feedback Speed Controller in DC Motor Using FOPID Fed with PSO

this paper, we introduced the much efficient dc motor speed Controller by using fractional feedback FOPID method. in simple PID we can change only gains of the proportional, derivative and integral controller. In FOPID method there are two more variable mu () and lambda () that we can adjust for obtaining faithful result. Here fractional feedback FOPID is used in placed of unity feedback for obtaining better performance. In which there are six variables that are three gains, two constant mu () and lambda () and one feedback constant is beta (). This paper will also give little view of particle swarm optimization by which we get optimized value of variable at which best result will occur.
