cascade control

A Cascade Control System uses multiple controllers in hierarchy to improve process control, stability, and disturbance rejection.

This application provides the cascade control system in the process control industry is a control strategy that uses two or more controllers arranged in a hierarchical manner to improve the performance of complex processes. It is typically used when a process has multiple interacting variables, where controlling one variable alone might not provide the desired performance.

In a cascade system, the primary controller adjusts the setpoint for a secondary controller, which directly controls the process variable. This approach allows for more precise and stable control by isolating disturbances and improving the response to setpoint changes.
