control theory is used in various fields including electronics and computer algorithms to solve problems of stability and convergence in systems that are influenced by both external stimuli and their own actions. In the context of distributed systems, control theory can help optimize the delay before issuing backup requests to improve reliability and responsiveness. The use of PID (Proportional Integral Derivative) controllers is a classic approach to achieve this goal, allowing for fine-tuning of how the system should behave to prevent overshooting, accumulating errors or unstable situations. By combining backup requests with PID controllers, systems can adapt rapidly to changing circumstances while minimizing resource usage and maintaining responsiveness.
