Nonlinear non adaptive backstepping with sliding-mode torque control approach for PMSM motor

Abstract EN

In this paper, the nonlinear non adaptive backstopping combined with the sliding mode torque and flux control approach for a permanent magnet synchronous motor drive is proposed.

We present a new contribution of FPGAs for control of electrical machines.

First, the adaptive backstopping control approach is utilized to obtain the robustness for mismatched parameter uncertainties.

The overall stability of the system is shown using Lyapimov technique.

The simulation results clearly show that the proposed not adaptive scheme can track the speed reference.

Secondly, the Indirect Sliding Mode Observer (ISMO) for permanent magnet synchronous motor (PMSM) speed and rotor position is used to realize sensor less control, we detailed description of the structure by Indirect Sliding Mode of Permanent Magnet Synchronous Machine PMSM.

Finally, some experimental results are demonstrated to validate the proposed controllers.

The experimental results carried from a prototyping platform are given to illustrate the efficiency and the benefits of the proposed approach and the various stages of implementation of this structure in FPGA.
