针对控制系统测量数据由模型误差和量测过程中产生的干扰问题,以及特定性能指标下最优控制问题,应用MATLAB GUI设计了一个方便用户操作、分析和处理各种测量数据的用户友好型界面。本文介绍了MATLAB GUI软件的相关知识,从测量数据如何建模、卡尔曼滤波、最优控制机制等方面进行了详细阐述。通过实例,利用开发的用户界面对某实验数据进行了分析、建模仿真试验,通过给定性能指标,得出了最优控制下控制量和状态量之间的关系。试验表明:用户界面实现了相应的功能,对提高控制系统数据准确度和增强系统智能化控制方面具有重要意义。

In view of the problem that the measurement data of the control system is caused by the model error and the measurement process and the optimal control problem of the specific function target, MATLAB GUI is used to design a user-friendly interface for user operation, analysis and processing of various measurement data. In this paper, we introduce the knowledge of MATLAB GUI software, how to model the data from the measurement data, and the optimal control mechanism of Calman filter. Through an example, the development of the user interface on a certain experimental data is analyzed, the simulation test, through the given function target, getting the optimal control of the relationship between the amount of control and state. After the experiment, the user interface has realized the functions, and has the important meaning to improve the data accuracy and the intelligent control of the control system.
