Abstract: This paper considers a method of synthesis of identification system for faults appearing in the various elements of complex mechatronic systems described by nonlinear differential equations.To solve this problem logic-dynamic approach and special feedback by residual signal is suggested.This approach consists of three main steps: replacing the initial nonlinear system by certain linear logic-dynamic system, obtaining the bank of linear logic-dynamic observers, and transforming these observes into the nonlinear ones.Logic-dynamic approach allows detecting and isolating faults in nonlinear dynamic systems by using the linear methods for diagnosis in nonlinear mechatronic systems.Feedback of special form introduced in the observers after the detection and isolation of faults.It is allowing to determine the value of faults in nonlinear systems with incomplete measurability of state vector.Efficiency and high performance of the proposed method is shown on example of identification of faults arising in electric drives of multilink manipulator.
