To address parameter faults in closed-loop control systems, this paper proposes a method that employs the K-gap metric to categorize the degree of parameter faults within the system. Corresponding controllers are then designed for each categorized fault level. In the event of a system fault, the K-gap metric is used to classify the fault, and a soft-switching mechanism is implemented to transition to the controller corresponding to the identified fault degree. This approach aims to achieve fault-tolerant control. The effectiveness and accuracy of this method are validated through an experimental setup involving a three-tank water system.

摘要

To address parameter faults in closed-loop control systems, this paper proposes a method that employs the K-gap metric to categorize the degree of parameter faults within the system. Corresponding controllers are then designed for each categorized fault level. In the event of a system fault, the K-gap metric is used to classify the fault, and a soft-switching mechanism is implemented to transition to the controller corresponding to the identified fault degree. This approach aims to achieve fault-tolerant control. The effectiveness and accuracy of this method are validated through an experimental setup involving a three-tank water system.
