Global Chaos Synchronization of the Brushless DC Motor Systems via Variable Substitution Control

The global synchronization of chaotic brushless DC motor (BLDCM) systems via variable substitution control is investigated. A master-slave synchronization scheme with variable substitution control is constructed at first. Based on this scheme, some sufficient criteria for global chaos synchronization of the master and slave BLDCM systems via various single-variable coupling are proved. The effectiveness of the obtained criteria is numerically verified by the examples.
