The concepts of parity equation residual quality as well as its fuzzy evaluation were presented to deal with the gradual fault in redundant SINS,and the residual quality was used to built the weighting matrix of least square,the intelligent adaptive fault tolerance for gradual fault was designed for redundant inertial instruments.Finally,the simulation results show that the method can detect and isolate no more than two soft faulty inertial components correctly.
