The switching frequency increases with the switching hysteresis of the controller. The smaller the switching hysteresis of the control device, the higher the fluctuation of the controlled variable and the smaller the switching frequency. The smaller the switching hysteresis of the control device, the smaller the fluctuation of the controlled variable and the higher the switching frequency. The fluctuation of the controlled variable is independent of the switching hysteresis – it only depends on the setpoint value. The bigger the switching hysteresis of the controller, the lower the fluctuation of the controlled variable and the smaller the switching frequency.Shown below is the control behavior of a level control when using three different controller types.
