Why is it important?
It can improve motor control and power electronic energy conversion of many kinds. It is in use for led drivers, but other DC-DC converters may also benefit from it. Peak current control in constant frequency is not always stable. Hysteresis control may tend to infinite frequency when the disturbance of signals is bigger than the hysteresis band. There is one drawback, that the usual processor technology are not made for such way of controlling.
Perspectives
The analog implementation is quite easy. The processor way is less easy. However, not impossible to realise. A similar use has been done in motor torque control. https://www.researchgate.net/publication/261420063_Programmable_Logic_Device_based_brushless_DC_motor_control
