LOW-SPEED SENSORLESS CONTROL OF PMSM MOTOR DRIVE USING A NONLINEAR APPROACH BACKSTEPPING CONTROL: FPGA-BASED IMPLEMENTATION

This paper presents a novel speed control technique for a permanent magnets synchronous (PMSM) drive based on newly nonlinear backstepping technique. We design a not adaptive speed regulator for a permanent-magnet synchronous motor (PMSM). In this paper, we present a new contribution of FPGAs (Field-Programmable Gate Array) for control of electrical machines. In this paper a robust continuous approach nonlinear not adaptative Control strategy for permanent-magnet synchronous motor (PMSM) drive systems is presented. This control scheme is based on an adaptive pole placement control strategy integrated to a Backstepping control scheme. The overall stability of the system is shown using Lyapunov technique. The simulation results clearly show that the proposed not adaptive scheme can track the speed reference. A bench test was realized by a prototyping platform, the experimental results obtained show the effectiveness and the benefit of our contribution and the different steps of implementation for the control FPGA.
