Fault isolation problem for sensor and actuator in nonlinear dynamic systems is studied. Parameter interval based fault isolation method has fast isolation speed and fits many kinds of nonlinear dynamic systems. This method is extended to the isolation of sensor fault and actuator fault. The example shows good performance.
