【摘要】 针对轧机厚控系统部分液压参数难以用机理分析方法准确获得的问题,本文应用系统辨识技术对300四辊轧机液压压下系统的进行可靠建模。通过对辨识结果对比与实验分析表明模型参数辨识是可行的,辨识结果也是可信的,这为系统设计,控制特性分析和实现最优控制奠定了基础。更多还原

【Abstract】 The article discussed the application of system identification technology to model building of hydraulic control system of automatic gauge control in 300 four-high mill .because it is hard to acquire the accurate value of some parameters by using the mechanical analying method. The model identification process proved to be feasible and the result to be creditable through the comparision and experimental analysis for the identified result. Thus, it established a foundation for system design and control characteristic analyzing and optimum control.更多还原
