ON THE GPI-PWM CONTROL OF A CLASS OF SWITCHED FRACTIONAL ORDER SYSTEMS

The control of a special class of Single Input Single Output (SISO) switched fractional order systems (SFOS), known as the relaxation-oscillation equation, is addressed from the viewpoints of the Generalized Proportional Integral (GPI) feedback control approach in combination with a Pulse-Width-Modulation (PWM) based Σ – Δ modulator implementation of an average model based designed feedback controller. An illustrative simulation example is presented.
