摘　　要：针对高速系统中存在的模型不确定性和外部扰动等问题,设计了基于内模原理的H∞高精度控制器。建立的伺服系统的数学模型将混合灵敏度问题转化为H∞控制问题。仿真结果表明,所提出的控制策略不仅具有较强的鲁棒性,而且改善了控制系统的动态性能,能够满足高速经编机要求的高速度、高精度、高响应和高频率启停的横移工艺要求。Aiming at the model uncertainty and external disturbance existing in the electronic shogging servo system of high speed warp knitting machine, the high precision controller based on internal model principle is designed. The mathematical model of servo system is established;the mixed sensitivity is transformed into H∞ control. The result of simulation shows that the proposed control approach not only has strong robustness and can improve the dynamic performance of the control system, this satisfies the requirements of warp knitting machine, including high speed, high accuracy, fast response and frequently startup and shutdown.
