Induction Motor Optimize Control in Field Weakening Region for Electric Vehicles Based on Expert Controller
摘要
Abstract
The induction motor drive inverter adopts digital controller and pulse-width modulation,caused the problem of digital delay,and with the parameter perturbation,reduced the control performance of the traditional indirect field oriented control for induction motor in the field weakening region.To solve this problem,an induction motor optimize controller in field weakening region for electric vehicles based on expert controller and fuzzy inference mechanism was proposed.Highly oscillatory or unstable response may occur if current regulators of the traditional indirect field oriented controller did not obtain proper current commands in the weak magnetic area.So the current reference of speed closed-loop output into the first expert controller firstly,then the expert controller changed the current reference based on database and fuzzy inference mechanism,and the fuzzy inference mechanism was realized by the simple Gauss logic function.Finally,a experiment platform for induction motor drive was built,and the high speed motor driving test was carried out.The test results verified the effectiveness of the new control strategy.关键词
