基于虚实结合实验平台的控制类综合实验课程建设

以控制类综合实验课程为基础,构建多层次的实验教学内容,并提出了基于虚拟仿真实验环境与便携式综合实验集成实验箱进行实验验证的虚实结合的实验教学模式。控制类综合实验内容以加热铜块和直流伺服电动机为被控对象,利用KeilμVision4集成环境与Visual Studio2012加载Measurement Studio工具箱完成代码编写,根据Matlab/Simulink对被控对象进行模型辨识与仿真分析完成控制器参数的设计。同时建立一套完整的课程考核体系,学生以小组形式充分利用线上与线下的时间、集中与分散的场地灵活地进行数据采集、代码调试、算法设计和实际操控以完成整个实验课程内容。     

不确定线性时滞系统的鲁棒故障诊断

1 Introduction Owing to the increasing demand for high reliabilityin manyindustrial processes , much attention has beenpaid to the problem of fault detection and diagnosis(FDD) in dynamic systems over the past two decades .Fruitful results can be found in a survey paper[1]andbooks[2 ,3]. It is well known that faults in a dynamic systemcantake many forms .They can be actuator faults ,sensorfaults ,unexpected abrupt changes of some parametersor even unexpected structure changes[4 ,5]. The pur-…
