Time Delay Feedback Control based Chaos Stabilization in Current Mode Controlled DC Drive System

 Abstract — This paper focuses on delay feedback control scheme to eliminate chaos in a current mode controlled DC drive system. The delay feedback method is applied for the current mode DC drive system which exhibits chaotic behavior for some parameter variations to control the chaos in DC drive system. Firstly, the change of system behavior from normal to chaotic operation is shown by changing some parameters. To control the chaos in current mode DC drive system, the controller designed based on time delay feedback control method is applied to DC drive system which works in chaotic regime. It is showed that the behavior of system changes from chaotic regimes to normal operation by applying the time delay feedback control.
