摘要
Abstract
To improve the brushless DC motor without position sensor control system,a new adaptive sliding mode observer was put forward to estimate rotor position and rotating speed,in which,a new type of switching function instead of traditional symbol function was constructed,a smooth line back EMF waveform measurement was obtained without low pass filter and phase compensation module,and then the rotor position was gotten. Based on Lyapunov stability theory,model reference adaptive algorithm was designed to estimate speed,and not affected by the switching ripple. Simulation and experiment results show that proposed method can accurately estimate the rotor position and speed,effectively restrain the torque ripple,improve the stability,rapidity and robustness of the whole system.关键词
