| Abstract: | A fault detection and identification method of actuators in dynamic systems based on fully - decoupled parity equations is presented in this paper. In order to detect and isolate actuator faults, the fully - decoupled parity vectors are used and the existence condition of fully - decoupled parity vectors is presented. A parameters estimate approach to actuator fault models is presented. In addition, a simulation example of a dynamic model is given. |
