Abstract: This paper proposes a highly accurate rotor position estimation method based on deadbeat predictive control and sensorless control using current derivative values. Compared with PI control, ...

Other important safety functions implemented in MCU software could be: The angle check is a critical safety mechanism ensuring that the rotor position aligns correctly with the expected values. This ...

Similar to Dynamic Skip Fire tech for diesel engines, Tula’s Dynamic Motor Drive intermittently operates the motor at high efficiency to deliver torque while minimizing losses at low loads.

First, we introduce the principle of UKF and estimate the rotor speed and position. Second, the parameter identification algorithm based on the UKF is given. Brief Introduction of the UKF and State ...

of a permanent magnet synchronous motor (PMSM) in a static coordinate system is accurately estimated by SMO, and then, PLL is constructed to combine the observed rotor position angle and back EMF to ...

Nowadays, horizontal well technology is being applied to the development of oilfield production capacity more and more. The horizontal well tractor can effectively solve the problem that the ...

Abstract: For the detection of rotor position in Permanent Magnet Synchronous Motor (PMSM), this paper presents an improved estimation method with switch ... simulations based on MATLAB/Simulink with ...

Thus a sixth-order Discrete-time Extended Kalman Filter approach is proposed for on-line estimation of speed, rotor position, load torque and stator resistance in a PMSM. The interesting simulations ...
