شرح پروژه
شبیه سازی مبدل کاک با فازی و pi و اسلایدینگ مود.Proportional-integral (PI) and sliding mode controls
are combined to regulate a fourth-order Cuk converter in a continuous
conduction mode. A closed-loop system is obtained with
the aid of the equivalent control method. Based on the Routh–
Hurwitz stability criterion and root locus, the appropriate PI gains
are obtained and a stable and robust system suitable for large signal
variations is achieved. The minimum or nonminimum phase
behavior of the closed-loop system and the transients of the closedloop
system under step variations of various circuit parameters are
analyzed. Under a wide range of operating points, the Cuk converter
under the proposed controller has a load voltage tracking
accuracy within±0.05V with a moderate maximum switching frequency
of not greater than 100 KHz. The merits and demerits of
the proposed controller are compared with some other controllers.
