Research on fault diagnosis of high precision servo simulator based on rough set theory

Based on the introduction to rough set theory, the realizing scheme of an electromechanical control system for a type of high precision servo simulator was proposed. Then, the rough set theory was applied the fault diagnosis of the simulator. Using decision table as a tool, the approach could extract diagnosis rules from the set of fault samples directly. The inherent redundancy in the high precision servo simulator was exposed. Practical application studies show the validity and reliability of the proposed scheme, and many hardware-in-the-loop real-time synthetic simulation tasks have been completed in this high precision servo simulator.
