在多变量系统中应用智能控制策略的新途径(英文)

A NOVEL APPROACH ON AN INTELLIGENT CONTROL STRATEGY IN MULTIVARIABLE SYSTEMS

讨论了建立在仿人控制特性基础上的方法及算法。文中着重解释了怎样才能把仿人控制策略(诸如真觉推理、控制特征识别及多模控制等)用于多变控制系统的问题。用文中所述方法构成的多变量控制系统在控制性能上具有确定的智能特性:系统直接在线从其运行过程中显示出来的特征获取信息;系统用一种与人处理问题相类似的方式来处理所获得的信息;系统中的控制策略是根据直觉推理来构成多模控制的;系统的控制器结构是分层建立的;为了解决系统中出现的严重耦合问题采用了协调器。计算机仿真结果验证了方法的有效性和可行性。

The methodology and algorithm based on human control behavior aredescribed in this paper.Specilically,an exposition is given to show how humaneontrol strategy(such as heuristics,control characteristics identiification and mul-ti-mode control,etc.)can be used to provide multivariable control system.Themultivariable control system formed by such a novel approach does have shown cer-tain intelligence in control performance:it obtains its signal information on-linedirectly from the characteristics displayed during operation transcient;it manipulatesthe obtained information in a manner analogous to how human would be;its controlstrategy and tactics are built on heuristics to form multi-mode control;its controllerstructure is built in hierachies;it uses the operation of a coordinator to solve the seri-ous interaction problems in the system.The efficiency and applicability of such anovel approach are demonstrated by computer simulation results.
