Abstract: Based on the direct torque control, combining the characteristics of both state-flux-oriented control and rotor-flux-oriented control, the scheme of speed estimation for motor in detail and calculation of related parameters are discussed. A simple and applicable speed estimation method of AC motor is put forward. A simulation experiment is carried out, it verifies the theory analysis is right and practical.

Key words: Direct torque control, Flux angle, Rotor-flux-oriented control, Speed estimation, State-flux-oriented control
