摘　　要：常规控制方法很难对变参数系统实现精确控制。建立精校机电液位置伺服系统离散数学模型,研究其常规控制方法。将极点配置自校正控制理论应用于精校机电液位置伺服系统中,提出该系统的极点配置自校正控制方法。仿真结果表明,系统的控制精度和跟踪性能将得以提高。The conventional control method is difficult to realize the precise control of variable parameter system.In the paper,we build the discrete mathematical model of electro-hydraulic position servo system for precise straightening press to study the conventional control method.We also introduced a method of pole as-signment self-tuning control of the electro-hydraulic position servo system of the precise straightening press by applying theory of pole assignment self-tuning control.The results show that the control precision of the system and tracking performance are improved.
