摘要
为建立轧机液压压下系统的精确虚拟样机仿真模型,提出基于干扰观测器控制的多平台联合仿真方案,根据轧机各辊之间的动力学关系,利用ADAMS、AMESim和Simulink分别建立了轧机液压压下系统的质量弹簧机械模型、液压位置伺服系统模型和PI反馈控制系统模型,通过接口互联构建了轧机压下系统多平台联合仿真模型。设计干扰观测器对控制模型进行改造,并通过对外部干扰噪声抑制的联合仿真进行验证,表明该控制器设计能够更精确的模拟轧机液压压下系统,该虚拟样机可应用于轧机液压压下系统分析。
In order to establish the precise mill hydraulic pressure system virtual prototype simulation model, program based on many platforms with disturbance observer is proposed. According to the dynamic relationship between every roll mill, a mass-spring model, hydraulic position servo system model and a PI position feedback control system are established by ADAMS, AMESim and Simulink. The AGC multi-platform co-simulation model is built through the software interface. The disturbance observer is designed to transform the control model to suppress the external disturbance noise, and it is proved right through joint simulation. The controller designed can be used in a more accurate simulation of the rolling mill hydraulic pressure system, and the virtual prototype can be applied to mill hydraulic pressure system analysis.
