Cascade Control

Cascade control is a method used in automated systems to improve precision and stability. It involves two controllers working in tandem: the primary controller sets the desired overall outcome, while a secondary (or inner) controller manages a specific part of the process more directly. The secondary controller's output feeds back into the primary, allowing for rapid adjustments and smoother performance. This setup is especially useful in complex systems where multiple variables need coordinated control, such as maintaining temperature while regulating flow, resulting in more accurate and responsive operation overall.
