摘要
研究了半闭环交流伺服系统的开环位移观测器数学模型 ,在传统伦伯格观测器基础上设计了滑模变结构观测器 .计算机仿真研究结果表明滑模变结构观测器可以较好地估计开环位移 ,提高了观测器的抗干扰能力 ,对于改进半闭环伺服系统的位置控制精度具有重要意义 .
A position observer with sliding mode using for the semi closed loop alterating current servo system is introduced. The proposed observer can perform the mechanism end position observing task better than traditional Luenberger observer. And computer simulations have shown that the observer works effectively with strong anti disturbance characteristics.
