| 摘 要： | 针对异步电机无速度传感器控制中用传统模型参考自适应理论估计转速时存在复杂的PI增益系数调节的实际问题,提出了一种基于趋近律的滑模模型参考自适应系统,并利用Lyapunov理论推导出一种新的速度估计自适应律以确保系统稳定性和快速性.同时,该方法对外部扰动和噪声具有强鲁棒性,且对抖振具有明显的抑制效果.通过Simulink仿真实验也验证了该方法响应速度快,控制精度高的优良性能.

| Abstract: | In order to solve the complex gain adjustment problem for induction motor speed sensorless by using the traditional Mode Reference Adaptive system,this paper presents a novel Sliding-Mode Mode Reference Adaptive System based on approach law,and use Lyapunov theory to ensure estimation stability and error dynamics.Meanwhile,this method has robust ability to external noise disturbance,and above all,has good effect on chattering reduction.Simulink simulation results also verified the good performance of quick response and high precision by proposed method. |
