摘要
永磁无刷直流电机在日常生活和工业领域中有着广泛的应用。随着控制要求的不断提升,传统双闭环永磁无刷电机控制系统已逐渐无法满足实际需求。针对控制要求,提出了内模控制与模糊控制相结合的驱动方式。在内模控制与双闭环控制相结合的基础上加入了模糊控制,电流环采用内模PI控制,转速环采用内模PI与模糊的共同控制。试验结果表明:基于模糊-内模控制的驱动系统在响应速度、超调量、转矩波动等性能方面与传统双闭环控制系统相比,都有明显优势。
Permanent magnet brushless DC motors had been widely used in daily life and industrial fields.With the continuous improvement of control requirements,the traditional double-closed-loop permanent magnet brushless motor control system had gradually failed to meet the actual needs.Aiming at the control requirements,a driving method combining the internal model control and the fuzzy control was proposed.On the basis of the combination of the internal model control and the double-closed-loop control,the fuzzy control was added.The current loop was controlled by internal model PI,and the speed loop was controlled by internal model PI and fuzzy.The experimental results showed that the drive system based on fuzzy internal model control had obvious advantages compared with the traditional double-closed-loop control system in terms of response speed,overshoot and torque fluctuation.
