| 摘 要： | 应用分层多模自适应滤波算法对控制系统的故障进行诊断时,只能识别出故障的类型,如识别出是传感器还是执行器发生故障,并不能判定出故障的大小.提出一种改进分层多模自适应滤波算法,应用此算法可使分层多模自适应滤波算法不仅可以检测出控制系统的故障类型,而且能够确定发生故障的执行器局部故障程度.将此算法应用于某无人机控制系统的故障诊断,仿真结果验证了该方法的有效性.

| Abstract: | The standard hierarchical multiple model adaptive filter algorithm can only be used to detect fault type.Based on this ordinary method,the paper puts forwards a new improved hierarchical multiple model adaptive filter algorithm which can not only detect the fault type but also determine the actuator’s fault degree.Simulation examples validate effectiveness of the algorithm. |
