摘要
This paper presents an adaptive-based fault detection and isolation scheme for a general class of robot manipulators, with characterizing the isolability conditions. The proposed algorithm consists of a nonlinear adaptive fault detection estimator and a bank of fault isolation estimators to determine the types of faults, which may be incipient or abrupt, while the fault parameter function may be time-varying. To demonstrate its effectiveness, the method is applied to a two-link robot manipulator and the simulation results are presented and discussed.
