In this paper, the yo-yo control system is introduced as a new benchmark system for evaluation of intelligent controllers. In order to control an yo-yo, an asymmetric nonlinear controller is needed due to the unique nonlinear asymmetric dynamic characteristics of the system. As such, it is difficult to control an yo-yo either by a linear controller or by a bang-bang controller. In the paper, we have implemented an yo-yo control system with a general-purpose fuzzy controller. In the fuzzy control, 14 if-then rules are used, being extracted from human expertise, and, for real-time control, a fuzzy inference hardware (called FLEXi) is used.>
