一类多输入多输出系统的冗余设计

摘要

The systematic integrity of the MIMO multivariable system when certain element failed is analyzed. In accordance with the open loop stable transfer function matrix and new decoupled objects are stable, the method of redundancy design for the system is given. The method effectively resolved the influence on stability when certain element failed and implemented the fault tolerant control for complex system. The result of simulation indicates that this redundancy design method is feasible and capable for implementing fault tolerant control of the system.%分析了多输入多输出多变量系统在某环节失效时系统的整体性,给出了针对开环传递函数矩阵以及解耦后新对象均为本质稳定对象时系统的冗余设计方法.该方法有效解决了某环节失效后对系统稳定性的影响,实现了复杂系统的容错控制.仿真结果表明,该冗余设计方法可行,能够实现系统的容错控制.
