Fault isolation problem for sensor and actuator in nonlinear dynamic systems is studied. In our previous work, we have put forward a parameter interval based method for nonlinear dynamic systems with respect to the faults of the dynamic part of the system. The parameter interval based method method fits many kinds of nonlinear dynamic systems, its isolation speed is fast. In this paper, this method is extended to sensor and actuator fault isolation problems for nonlinear dynamic systems. The example using the single-link robotic arm model shows good performance of this method for sensor and actuator fault isolations for nonlinear dynamic systems.
