GFD233 3BHE022294R0102 Redundant System Control

Redundant system control refers to the use of multiple controllers or components in a system to provide backup or redundant functions to ensure the reliability and stability of the system.
Redundant system control is often used in critical systems, such as power, aerospace, medical, and industrial control, where system failure can lead to serious consequences.
In redundant system control, there is usually a primary controller and one or more backup controllers. The primary controller is responsible for performing the main control tasks, while the backup controller is in standby state and waits for the primary controller to take over the control tasks when it fails.
Redundant system control can be realized by many technologies, such as hardware redundancy, software redundancy and network redundancy. Hardware redundancy usually uses multiple controllers or components to provide backup functions, while software redundancy is achieved by copying control software. Network redundancy ensures the reliability of communication by using multiple network paths.
Redundant system control can improve system reliability and stability, reduce the risk of system failure, and ensure that the system can recover quickly in the event of failure.
