Fuzzy PI Self-tuning Control of Flux and Torque of Induction Motor DTC
摘要
Abstract
In order to overcome torque ripple at low speed and switching frequency uncertainty of the tradition at Direct torque control (DTC) , self-tuning fuzzy PI controller based on flux and torque was designed to reduce the torque ripple, which is based on error and error change rate of flux and torque, control parameters are realtime online adjusted to improve control performance of torque and flux. On this basis, a control scheme with twelve voltage space vector DTC space vector modulation was presented. Any required voltage space control vector could be synthesized using the subdivision twelve voltage space vectors. Simulation and experimental results show that the system can obtain more precise control of torque and flux, reduce torque ripple at low speed and improve ability of adaptive control of the DTC system.关键词
