Virtual Speed Sensorless Desired Control Strategy of Maglev Single-sided Linear Induction Motors
摘要
Abstract
Single-sided linear induction motors (SLIMs), with short-primary long-secondary structure, have been broadly used in the intermediate speed range maglev traction drivers. Some parameters of SLIM parameters are nonlinear time-varying greatly for the reason that the equivalent circuit models, considering the end-effect, are asymmetrical. And the traditional speed sensorless methods implied in rotate-motors are invalid or unreliable. This paper first analyzed the M/T equivalent circuits of SLIM and selected the secondary flux as speed observation status variable. From requirements of Lyapunov principal for a stable system, it deduced the speed sensorless identification function suitable for SLIM. Then a feedback-type general integrator observer was used to control the pulse vibration double amplitudes of stable speed. With the estimated speed, it adopted a virtual desired variable (VDV) method to achieve constant sliding frequency vector control of maglev SLIM. The effectiveness of the proposed algorithm is verified through the simulated and experimental results.关键词
