A novel adaptive cascade controller design on a buck–boost DC–DC converter with a fractional?order PID voltage controller and a self?tuning regulator adaptive current controller

The design of a cascade controller is demonstrated for buck–boost converter that combined with two control loops consisting inner and outer controllers. loop implemented by fractional-order proportional-integrated-derivative (FO-PID) works as voltage generates reference current the loop. To provide faster dynamic performance loop, self-tuning regulator adaptive controller, which tries to regulates help novel improved exponential regressive least square identification in an online technique, designed. Moreover, tune gains FO-PID algorithm antlion optimizer used offers many benefits comparison other algorithms. system provided boost mode non-minimum phase system, creates challenges designing stable controller. In addition, single proposed based on PID tuned particle swarm optimization be compared Cascade can present significant such better disturbance rejection. Finally, strength presented scheme verified different performing situations real-time experiments.
