The article concerns observing states of the Induction Motor (IM) using a Luenberger observer in the speed servo drive. The movement of the motor and observer roots is analyzed for a variable speed. Following the analysis, a new method for gain e

An FPGA-Based servo controller for permanent magnet synchronous motor (PMSM) drive is designed and realized in this paper. The FPGA-Based controller has two modules. One module performs the function of the current/speed loop control for PMSM
