FuzzyModelandControl forHybrid Systems Using Averaging Techniques
Kuang‐Yow Lian · 2006
Hybrid systems areusually consisted ofstates described partially bycontinuous variables andpartially by discrete variables. Inthis work, wepropose anLMI-based control design forhybrid systems byusing fuzzy model-based approach andaveraging method. We start withthecontrol-oriented presentation todefine thehybrid automata. Then, it isdescribed byafuzzy model. Inlight oftheconcept ofpulse-width modulation (PWM)scheme, thecrisp fuzzy setis withthevalue oftheduration inaninterval. Instead ofdirectly designing theswitching sequence forourhybrid systems, thevalues oftheduration arethecontrol signals whichneedtobedesigned. Then, theswitching sequence forthehybrid systems canberealized byusing PWM method.
