“…This control law can be considered as an alternative to PI and PID controllers [11] and the performances are really satisfactory taking into account that the control is calculated based only on the information provided by the controlled input and the measured output signal of the controlled systems. This control law has been extensively and successfully applied to control many nonlinear processes: see, e.g., [3,10,12] and the references therein. In particular, some applications have been dedicated to the control of chemistry and biological processes [2,3,13,17,26], including the development of an artificial pancreas [16].…”
