基于未知输入观测器的悬架故障诊断

Suspension fault diagnosis based on unknown input observer

首先将故障作为观测器的未知输入,从而通过观测器的设计来解耦故障与系统状态,然后用公式来统一描述悬架系统执行器故障、传感器故障以及元器件故障。Simulink仿真实验验证了观测器的可行性。

First, faults are regarded as the unknown inputof the observer （UIO） tO decouple the faults and system states. Then, a formula is built to describe the actuatorfaults, component failures and sensor faults for the suspension system. Simulation verify the feasibility of the observation.
