Abstract: A new method of fault tolerant control for multiloop SOSI system is suggested.A reconfiguration control rule is applied to the neighbouring loop of any fault sensor for compensating its effect.The suggested method is able not only to maintain the stability of the system but also to keep the controlling quality to be the same as that before the fault happens.This method is suitable for both minimal and non minimal phase systems.The results of the numerical simulation show that the method is of good compensating function.
