摘要：在最优控制系统设计中,由于二次型评价函数和闭环系统的关系不明,往往采用试探法选取加权矩阵Q、R。这样不仅难以选定最优参数,也给控制系统的现场调试带来了很大的困难。本文阐述了一种选取加权矩阵的新方法——零点追加法。

摘要：本文从理论上分析了LQ 问题逆推法解的存在性和唯一性,给出了二次型最优闭环系统在频域内的两个必要条件,以及单输入线性定常可控系统逆推法解存在的充分必要条件。所得结论对于设计一个具有预期闭环极点的最优控制系统有着很重要的指导意义。最后推导出二阶系统两个主要动态参数ξ,ω_n 与权阵 Q、最优反馈阵K 以及被控系统参数之间的关系。

摘要：当今,描述系统的理论有许多,灰色系统理论就是其中独具特色的一种。灰色系统理论认为:对系统内部结构特性确知的应是白色系统;对系统内部结构特性未知的则是黑色系统;对系统内部结构特性时明时暗或有知有惑的,称之为灰色系统。人体是一个系统,人体的外形参数,如身高、体重。

摘要：从偏差系统出发,利用目标值信号的二阶差分进行最优预见伺服系统设计的方法。这种设计方法适用于有输入时间滞后的线性控制系统。

摘要：Manufacturing plants are increasingly complex and integrated, requiring control systems able to identify the interactions between the various operating units. Production planning and control design of a process are tools that, if combined, bring many economic benefits to the processes since they aim to identify and maintain optimal decision operations to a system. This work uses such integration between production planning and plantwide control to propose a control system for the Williams-Otto plant from the definition of the operating optimal point for coordinated decentralized optimization, in which the original optimization problem decomposition into smaller coordinated problems ensure that the found local optimum also meets the requirements of the global system. The results for decentralized optimization are satisfactory and very similar to the global optimum problem and to the control system response proposed based on the optimal obtained. It is effective taking smooth actions, working with (economic) optimal set points (economically) of operation. The unification of production planning techniques and plantwide control techniques is an effective tool for the control system design for entire plants.
