Direct Torque Control of Interior Permanent Magnet Synchronous Motors Based on Sliding-mode Active Flux Observers
摘要
Abstract
A sliding-mode observer based on"active flux"concept was proposed. Different from the conventional stator flux linkage observer,this observer was not consisted of the speed adaptive loop. Therefore,it was immune to estimate of speed error which would make the performance of the observer worsen. The Lyapunov stability theory was employed to prove that the observer was asymptotically stable. By using the estimated active flux angle,the motor speed could be calculated. As a result,the speed sensor-less IPMSM direct torque control drive was achieved. Simulation results are presented to validate the effectiveness of the proposed method.关键词
