Sensorless Control of Induction Motors Using an Extended Kalman Filter and Linear Quadratic Tracking

摘要

Conventional sensorless controls for induction motors require two PID regulators and precisegain turning. This thesis presents a sensorless control for induction motors using an extendedKalman filter (EKF) and linear quadratic tracking (LQT). The proposed method requiresonly a single controller and no physical velocity sensor
