Abstract
The adaptive backstepping and smooth switching control method of rotor flux is investigated in the paper to achieve precise speed tracking control and minimum loss of induction motor. When the uncertain load first appears in the recursive design, the adaptive law of the load is designed, and the unknown load is estimated by novel adaptive load torque observer. By introducing the switching term into the ESO of ADRC, the current loop can converge rapidly to the desired current. And the smooth switching control method among the rated and the minimum rotor flux has been studied, which achieving the minimum loss of induction motor. The results demonstrate that the novel adaptive load torque observer acquire quick tracking of unknown load torque, and the smooth switching control method saves the loss of induction motor when it is in stable state.
