A simplified current control method which enables an inverter to generate 20 kinds of space voltage vectors is developed, and a digital signal processing (DSP) based software field oriented induction motor drive system using this method is also presented. In this system, a particular sampling technique is used to shorten the dead time in the current control(More)
A description is presented of the fuzzy proportional-plus-integral controller for the vector control system of an induction motor, and the performance of the system using this controller is discussed. The theoretical process of the fuzzy inference and the guide to a design of the controller are presented. This controller is applied to the laboratory model(More)
It is widely accepted that an efficient flood alarm system may significantly improve public safety and mitigate economical damages caused by inundations. In this paper, a modified adaptive neuro-fuzzy system is proposed to modify the traditional neuro-fuzzy model. This new method employs a rule-correction based algorithm to replace the error back(More)
