摘要:
传统异步电机闭环控制中转速和磁链外环采用比例积分(PI)控制,针对其有超调和动态响应慢等问题,提出了一种新型的滑模控制器用于外环转速和磁链控制,改善了动态性能。采用五阶扩展卡尔曼滤波(EKF)来估计转速和磁链并用于闭环反馈,进一步研究了引入转矩观测后的六阶EKF,考察了转动惯量对速度估计的影响,在三电平逆变器驱动异步电机平台上进行了各种实验。结果表明,基于EKF和滑模控制的无速度传感器控制系统在较宽的速度范围内具有良好的动静态性能。
Abstract:
Proportional-integral(PI) controller is widely used in conventional closed-loop control of induction motor drives.However,there usually exist problems of overshooting and low dynamic performance.A novel sliding mode control(SMC) was proposed for speed and flux regulation to enhance the performance of outer loop.A fifth-order Extended Kalman Filter(EKF) was employed to observe the rotor speed and flux.Furthermore,a sixth-order EKF including torque observation was investigated,which considered the effect of m...
