Recent successful fuzzy logic applications in industrial automation

In this paper we review eight recent applications of fuzzy logic in industrial automation. All applications used the so-called "fuzzy programmable logic controller (PLC)", an innovative hardware platform that merges fuzzy logic and traditional automation techniques. Following a quick overview on the fuzzy PLC, we discuss the applications and focus on how fuzzy logic enabled a superior solution compared to conventional techniques. We quantify the benefit of fuzzy PLC in cost saving or quality improvement.
