Recently, digital signal processors (DSP's) are becoming more popular in the area of ac motor control, in particular the induction motor drives. The fast number crunching capabilities of DSP's which are traditionally meant for data processing tasks such as image processing and speech recognition, are being utilised to perform on-line calculation of the ac motor variables, such as electromagneti...

Scientific considerations presented in this paper are related to the methods for power loss minimization in induction motor drives. The induction motor is without doubt the most used electrical motor and a great energy consumer. Three-phase induction motors consume 60% of industrial electricity and it takes considerable efforts to improve their efficiency (Vukosavic, 1998). The vast majority of...

Robust control of a decoupled induction motor drive is attempted in this paper. Sliding Mode Controller and Fuzzy Sliding Mode Controller are designed for the speed loop of the drive. The design steps for both the controllers are laid down clearly. Only four fuzzy rules, and Center-ofSums defuzzification technique are used in the fuzzy controller for simplicity reasons. The performance of the f...

The efficiency of induction motor drive under partial load can be improved via manipulation of its field excitation. Among the numerous efficiency optimization schemes previously proposed, the scheme that uses motor power factor as the main control variable has the advantages of high sensitivity and ease of implementation. Because the optimal power factor is a function of motor speed and is sen...

Induction motor (IM) control has drawn considerable attention in the past decade due to its wide range of application in industry.
