Abstract :
This paper proposes the stability analysis for the fuzzy pulse-width-modulation (PWM) system which based on intelligent digital redesign (IDR) method. The term IDR is to convert an existing analog control into an equivalent digital one in the sense of state-matching. The IDR problem can be reduced to find the digital gains minimizing the norm distance between the closed-loop states of the analog and digital control. The redesigned digital controller is again converted into PWM controller for stabilizing the fuzzy PWM system.
