Optimal FOPI-FOPD controller design for rotary inverted pendulum system using grey wolves’ optimization technique
The rotary inverted pendulum (RIP) has been used in various control
application areas. This system can be represented as two degree of freedom
(2-DOF), consisting of a rotating arm and rotating pendulum rod. RIP is an
excellent example of…
