This paper presents a novel control strategy translating to scalar control some energy saving control laws proposed for vector control, and forces the induction motor drive to operate at a suitable slip angular frequency, assuring loss reduction of the drive. Energy saving capability, parameter variation effects, and dynamic behavior of the scalar control technique are analyzed and experimentally...
This paper proposes a low-cost implementation of energy saving strategies in scalar control IM Drives including high speeds in a wide working range. This loss reduction control algorithm approximates and adapts to scalar control some optimized analytical relationships, proposed in vector control, for low cost implementation. Basically an “optimal” slip from the energetic point of view is calculated...
