Description: Paper about a new close loop current model flux observer to estimate the rotor flux, position and velocity of an induction machine. The current observer includes carefully designed sliding mode functions which are derivative of the fluxes along the and axes. Therefore, when the estimated current converges to the measured one, the flux estimation is a mere integration of the sliding mode function.

Description: 异步电机的精确控制和速度辨识是交流传动系统中重要问题。在该仿真系统中，电机转速采用易于检测的电机定子电压和电流得到转速MRAS辨识算法来估算。由于速度辨识算法中电压模型的纯积分环节会引起的误差积累和漂移问题，采用改进积分型转子磁链估算模型来解决。-The precise control and the speed identification of AC motor are the very important issues on AC drive system.In this system, induction motor is controlled by the direct torque control, stator flux is estimated by u-n model observer that is effective in the full range of speed, motor speed is estimated by MRAS speed identification algorithm that is depended on the voltage and the current of motor stator easily detected. The modified integral rotor flux estimation model is used to solve the problem that the normal model can be affected by the error accumulation and drift of integral calculation in the voltage model of conventional speed identification algorithm.

Description: The article concerns observing states of the Induction Motor (IM) using a Luenberger observer in the speed servo drive.
The movement of the motor and observer roots is analyzed for a variable speed. Following the analysis, a new method for
gain evaluation of the IM magnetic flux observer is presented. This structure is extended by including an adaptive speed
observer. The functionality of the presented method is proved in simulations using MATLAB Simulink.

Description: sensorless induction motor drive is presented, in
which the principles of sliding-mode control, direct torque control
(DTC), and space-vector modulation are combined to ensure
high-performance operation, both in the steady state and under
transient conditions. Merits of the classic DTC transient behavior
are preserved, while the steady-state operation is significantly improved.
The torque and flux controllers, and motor state observer
are of the sliding-mode type. The inverter is directly controlled on
the basis of torque and flux errors, using space-vector pulsewidth
modulation. Computer simulations and experimental
