摘要：In this paper, the nonlinear non adaptive backstepping combined with the slidingmodetorque and flux control approach for an permanent magnet synchronous motordrive is proposed. we present a new contribution of FPGAs for control of electricalmachines. First, the adaptive backstepping control approach is utilized to obtain therobustness for mismatched parameter uncertainties. The overall stability of thesystem is shown using Lyapunov technique. The simulation results clearly show thatthe proposed not adaptive scheme can track the speed reference. Secondly, theIndirect Sliding Mode Observer (ISMO) for permanent magnet synchronous motor(PMSM) speed and rotor position is used to realize sensorless control, we detaileddescription of the structure by Indirect Sliding Mode of Permanent MagnetSynchronous Machine PMSM. Finally, some experimental results are demonstratedto validate the proposed controllers. The experimental results carried from aprototyping platform are given to illustrate the efficiency and the benefits of theproposed approach and the various stages of implementation of this structure inFPGA.
