Implementation of Fuzzy Controllers for Industrial Applications
Zdenko Kovacic, Stjepan Bogdan · 2018
The fuzzy control technology has emerged as one of the most effective nonlinear control technologies used in industrial applications. Everything began in 1970s with pioneering work of E.H. Mamdani and first successful application of fuzzy logic for steam engine control [1], followed by contributions of many other eminent fuzzy control scientists and engineers [2-7]. Since then the spectrum of fuzzy control applications is steadily growing. Thanks to the joint efforts of university and industry research teams all over the world, in 1980s and 1990s, a “fuzzy boom” happened in various application fields. For example, fuzzy control found its way in traffic control and transportation [8-10], process industry [11-15], robotics [16,17], flight control [18-20], but even more important, in short time the fuzzy control has become a standard solution in a large number of consumer products such as photo cameras, washing machines, air-conditioners, and many others. In this early fuzzy control stage, Japan was leading in the number of registered patents and launched new products (especially leading companies such as Omron, Fuji, Hitachi, and Matsushita). Excellent reviews on the historical development of fuzzy control engineering and numerous applications can be found in References 21 and 22.
