摘要
针对伺服系统防振控制问题 ,在所建弹性臂数学模型基础上 ,引入 H∞ 混合灵敏度设计方法 ,讨论各加权函数选取 .仿真结果表明 ,H∞ 混合灵敏度方法具有一定的优势 ,它对于对象的不确定性有一定鲁棒性 ,同时也具有良好跟踪性、抗干扰性 ,它不失为该领域富有潜力的、新的研究方向 .
To prevent vibration in a servo system, an approach of H ∞ mixed sensitivity based on the model of flexible arm is introduced, and weighted functions are discussed. This approach has advantages in robustness against uncertainty, and abilities in position tracking and disturbance rejection, therefore provides a potential research direction in this domain.
