Active Fault Tolerance Control Based on Consistent Matrix for Multimotor Synchronous System

Active Fault Tolerance Control Based on Consistent Matrix for Multimotor Synchronous System

This paper presents an active fault-tolerant method to mitigate sensor failures in multimotor synchronous control. First, inspired by the construction of the coupling matrix in complex network synchronous output, a consistent matrix is designed based on structural redundancy in synchronous control....
