研究了具有执行器故障的双线性随机分布系统的故障诊断与容错控制问题。首先，基于粮食加工装置，建立了双线性随机分布系统模型。然后，设计一种新的未知输入观测器进行故障诊断，并根据估计的故障信息设计模型预测容错控制器，使系统在故障发生后保持稳定或仍保持控制性能。最后，通过粮食加工过程验证了该算法的有效性。
In the paper, the problem of fault diagnosis and fault‐tolerant control for the bilinear stochastic distribution system with actuator fault is studied. Firstly, based on a grain processing device, a bilinear stochastic distribution system model is established. Then, a new unknown input observer is designed to diagnose the fault, and a model‐predicted fault‐tolerant controller is designed for the system on the basis of the estimated fault information, in order to keep the system stable or still maintain the control performance after the fault occurs. Finally, the validity of the proposed algorithm is verified by the grain processing process.
