Largest of maximum (LOM) method for switching fuzzy control system

Switching control systems are inexpensive and provide signals to activate or deactivate the system actuators. In this paper, fuzzy logic controllers, which produce switching signals have been developed using largest of maximum (LOM) defuzzification method. Two control schemes of two-level and three-...
