Estimation Scheme

Based on stator-field-orientation control combining with both direct torque control (DTC) and rotor-field-orientation control a speed estimation scheme is presented in this paper. Two key problems are discussed in detail. First is to use phase operation to decide stator-field-orientation angle θs and then the discrete-tracking-differential (DTD) technique is employed to high quality stator current. The experiments show that accurate speed estimation can be obtained by the method.
