Current Control of BLDCM Based on Fuzzy Adaptive ADRC

2009 Ninth International Conference on Hybrid Intelligent Systems, 2009
To solve the problems associated with conventional PID control for brushless dc motor (BLDCM), such as high current and torque ripple, a new current controller based on fuzzy adaptive active disturbance rejection control (ADRC) are proposed in this paper. The mathematical model of the motor and the principle of ADRC are analyzed. Fuzzy reasoning method

The Switching Time Research of BLDCM for Fuel Pump

2018 2nd IEEE Conference on Energy Internet and Energy System Integration (EI2), 2018
The brushless DC motors for Aviation fuel pump use Hall position sensors to get the position of rotor in motors. The rotors' switching time would be advanced or delayed because of the angle error in Hall position sensors. In order to ensure the motor run reliably, the switching time has to be determined accurately.

GA based PI control of BLDCM Drive

2008 27th Chinese Control Conference, 2008
The brushless DC motor (BLDCM) has a good control performance. The classical PI controller is widely used controller. But the determining of its parameter needs the mathematical model of the system. Usually the exact mathematical model of system is hard to known. This places a restriction on the applying of the commonly used Z-N method to determine the
