Abstract :
This paper presents a hysteresis band controller in charge of fixing the switching frequency of a sliding mode controller. The proposed control measures the switching period of the control signal and modifies the hysteresis band of the comparator to regulate the switching frequency of the sliding motion. The switching frequency control system is modelled and a design criterion of the control parameters is derived to guarantee the closed loop stability.
