Sensorless BLDC Control Method

2020 IEEE 26th International Symposium for Design and Technology in Electronic Packaging (SIITME), 2020
This paper proposes a new control method for BLDC motors using sensorless trapezoidal control capable of regenerative braking, designed to be used on low-power and moderate computational power microcontrollers. It exhibits good performance on systems where the load does not have abrupt changes over time and the requirements for efficiency are not very ...

Sensorless Drive Control

IFAC Proceedings Volumes, 1989
Abstract The digital control of electrical drives by microprocessors requires special control concepts which are formed for digital signal processing. By implementing the well-known control strategies in the frequency domain and in the state space there are always two fundamental disadvantages; first the nonlinearities of a drive system cannot be ...

Sensorless control for synchronous motors

2010 International Conference on Autonomous and Intelligent Systems, AIS 2010, 2010
Permanent magnet synchronous motors are used in many industrial applications because they have several inherent advantages. However, information about the rotor position is necessary even to be able to control drive speed. Conventional speed and position detection uses encoder and resolver.

Sensorless control for linear compressors

International Journal of Applied Electromagnetics and Mechanics, 2006
A closed-loop sensorless stroke control system for a linear compressor has been designed. The motor parameters are identified as a function of the piston position and the motor current. They are stored in ROM table and used later for the accurate estimation of piston position. Also it was attempted to approximate the identified motor parameters to the

VHFIM sensorless control of PMSM

2010 IEEE International Symposium on Industrial Electronics, 2010
The paper deals with combined real-time model of PM synchronous motor for sensorless position control. Real-parametric-and real-time model could be ideal tools for both control and simulation of the PMSM position drive. Unfortunately that idealized model doesn't exist so far.
