Abstract


This paper treats several application-oriented fuzzy control solutions with Takagi-Sugeno fuzzy controllers (TS-FCs) developed for mechatronic applications. Low-cost fuzzy control solutions are offered with simple design approaches and easy implementation results. The solutions are organized such that to represent useful recommendations for specialists who apply artificial intelligence techniques in wide range of practical applications related to mechatronic systems. It is proved that our fuzzy control solutions can ensure good control system performance and compensation for plant nonlinearities in mechatronic systems as well. Therefore they enable the application and full utilization of such systems. Three case studies related to the speed and position control of three mechatronic applications are included: a vehicular power train system with continuously variable transmission, an electromagnetically actuated clutch and a magnetic levitation system. Plant models expressed as first principle nonlinear models and linearized models are offered. Simulations and real-time experimental results validate the low-cost TS-FCs.
