Abstract: Basic theory system for fault tolerance and fault rectification design of ElectroMechanical Products (EMPs) was proposed based on research of notion and method of modern product design as well as modern control theory. Primary framework for software system of fault tolerance and fault rectification design and simulation of EMPs was constructed. Key technologies of fault tolerance and fault rectification design were studied. To realize fault tolerance and fault rectification design of EMPs, studies on this software system provided feasible theory, effective method and digitaloriented integration environment. Design process of fault tolerance and fault rectification was described in detail by an example of collisionavoidance robot. Simulation results proved that the fault tolerance and fault rectification design could guarantee the safety and reliability of EMPs.

Key words: electromechanical product, fault tolerance, fault rectification, redundant, fault diagnosis
