Opis

High performance electric motor drives are considered an essential requirement for modern industrial applications. Accurate speed information is necessary to realize high performance and high-precision speed control of induction motor drives. Direct speed sensors imply additional electronics, extra wiring, extra space, frequent maintenance and careful mounting which detracts from the inherent robustness and reliability of the drive, and an extra cost. Many advantages of speed-sensorless induction motor drives such as reduced hardware complexity, low cost, reduced size, elimination of direct sensor wiring, better noise immunity, increased reliability, and less maintenance requirements. Speed-sensorless motor drives are also preferred in hostile environments and high-speed applications. Robust Sliding Mode Observer for Sensorless Induction Motor Drives with Parameters Estimation. Hybrid Chatter-Free SMO. Speed and Stator Resistance Identification Schemes of Sensorless Induction Motor Drives. Operation of Speed-Sensorless Induction Motor Drives in the Field Weakening Region Considering the Flux Saturation.
