Optimal synchronizing speed control of multiple DC motors

In this paper, optimal synchronization speed control of multiple DC motors is developed by using leader-follower based approach. One of the DC motor is considered as a leader motor and it tracks its desired speed trajectory. The other DC motor is controlled through a leader-follower based optimal formation controller developed in this work. If the leader DC motor slows down or speeds up for some reason, the follower DC motor synchronize its speed according to the leader without having any knowledge about the desired trajectory. By doing so, the multiple DC motors will be able to work together in a synchronized manner. The simulation results are given at the end of the paper to verify our theoretical claims.
