Control of induction machine supplied by a current source inverter using the multi-scalar transformation and backstepping approach

The paper describes the voltage control technique of squire-cage induction machines supplied by a current source inverter. The control system is based on new transformation of the electric drive system (machine and inverter) state variables to the multi-scalar variables form. The backstepping approach is used to obtain the feedback control law. The control system contains the structure of the observer backstepping which is named Z. The paper contains the theoretical analysis of the control system with the new multi-scalar proposed transformation. The control system performances and mathematical dependences are confirmed by the experimental results.
