基于PI参数自适应的开关磁阻电机调速控制研究
Speed Regulation Control of Switched Reluctance Motors Based on PI Parameter Self-adaptation
摘要
Abstract
Doubly salient structure and its easy magnetic saturation characteristics of the switched reluctance motor (SRM) cause nonlinear inductance profiles,and the output torque varies with the current and the rotor position.The parameter self-adaptation speed regulator and the current regulator will effectively improve the operating performance of the SRM speed control system. According to the characteristics of SRM,the paper presented a PI parameter self-adaptation current regulator using the DC motors current loop correction technique,and a speed regulator using the DC motors speed loop correction technique and the small-signal analysis method, where the current loop was the inner loop, and the speed loop was the outer loop. Due to the effects of torque ripple was greater when SRM running at low speed,the dual operation mode was designed to follow the speed regulation for improving the torque ripple. Indirect torque-current control was employed when SRM running at low speed, where the output of the speed regulator was used as the reference torque, and thereby regulating the reference current to reduce torque ripple. Direct current control was used when SRM running at high speed, the output of the speed regulator was used directly as the reference current. Finally, the simulation and experimental results demonstrate the feasibility of the control scheme.关键词
