摘要
The present invention is an angular position sensor-less control method of the high-efficiency permanent magnet synchronous motor for emergency operation one to precisely detect the magnetic pole position of a synchronous motor through a vector control angular position sensor-less Using Adaptive Observer-based permanent magnet synchronous motor model It relates. ; That is, the present invention, while the voltage and the measured current applied to the motor from the approximated synchronous coordinate current differential equation model based on the magnetic pole position estimated based on a mathematical model of a permanent magnet motor as input the position error and the speed error information is the magnetic pole position that configure the considered adaptive observer, and by applying an adaptive law (adaptive law) therefrom using the obtained position error PLL (Phase Lock Loop) controller, to create a magnetic pole position error of the synchronous motor to zero angle of the high-efficiency permanent magnet synchronous motor for driving an emergency to be estimated position sensor-less control method intended to provide. ; The synchronous motor, a permanent magnet, the magnetic flux, the magnetic pole position, position error, the adaptive observer, differential equations, sensor-less control method
