Periodic operating modes of pulse-width control systems. II (Q1111501)

[For the first part, see the authors, Avtom Telemekh. 1987, No.11, 46-54 (1987; Zbl 0647.93038)]. Here the existence of the periodic modes for pulse-width modulation (PWM) systems of the second kind is investigated. After establishing the equation which governs the behaviour of such systems, an algorithm to solve this equation is presented. Then, some theorems are proved which give sufficient conditions for the existence of periodic modes and for the possibilities of disrupting periodic modes. Finally, we think the whole paper, part I and part II, constitutes a deep and interesting analysis of PWM systems and its translation into English is welcome.
