control of induction machine supplied by current source inverter

What is it about?

It is about Control system of induction motor which is named 'sensorless' because the electrical speed is not measures only estimated by the Z backstepping observer. The control system is based on multiscalar variables and the classical feedback control law. The author proposed new state variables transformation. The control variables are the dc-link voltage and output current vector angular speed. The experimental results are shown.
