Motor system with mechanical position sensor has lower reliability and higher cost. Sensorless control of brushless DC motor (BLDCM) has been focused recently and many intelligent methods are being tried to realize sensorless control. In this paper, the relationship between rotor position of BLDCM and phase voltages is analyzed firstly. Then, a sensorless control method using support vector machine...
The brushless DC motor has such advantages as simple structure, convenient to control, high reliability, and has been applied in many industrial fields. In order to simplify the converter topology and lower the system cost, four-switch three-phase BLDCM recently becomes research highlight of scholars. Conventional hysteresis controllers suffer from big phase current ripple and inaccuracy current threshold...
Cost minimization is the key to the large volume manufacture and application of the brushless DC motor. A novel four-switch three-phase brushless DC motor drive based on variable threshold direct current control is proposed to lower cost and improve performance. The real-time current threshold identifier working based on speed error and current of DC link, is made up of a radial basis function neural...
The brushless DC motor (BLDCM) is a multi-variable and non-linear system, so it is difficult to get a satisfying result for BLDCM using the conventional linear control method. This paper presents an approach of single neuron PID adaptive control for BLDCM based on wavelet neural network on-line identification. The method uses single neuron PID to construct the adaptive controller of BLDCM. In addition,...
The brushless DC motor (BLDCM) has such advantages as simple structure, convenient to control, high reliability, high efficiency, and has been applied in many industrial fields. Conventional controllers suffer from uncertain parameters and the nonlinear of the BLDCM. To overcome the shortcomings of the conventional controller, this paper presents a novel strategy on the basis of compound control using...
