Intelligent fault diagnosis and fault-tolerant control
Fault Detection and Diagnosis (FDD)
Detect the fault information of the monitored object and make judgments on the fault, cause, type, location and degree
Get fault information
Find the source of the fault and determine the location, size, type and cause of the fault
Evaluate the degree of impact and predict development trends
Make decisions and process results
basic requirements
Strong detection capability
Strong diagnostic capabilities
Modular structure
Human-machine interactive diagnostic function
Multiple ways to obtain diagnostic information
Problem solving is real-time and accurate
Has learning function
Have the ability to predict
Have decision-making ability
Intelligent detection and diagnosis
Fault Tolerant Control (FTC)
According to the fault information provided by FDD, use fault-tolerant control strategies to compensate, suppress, weaken, and eliminate faults.
Purpose
Isolate the faulty part and use fault compensation, system reconstruction, structural redundancy, and failover without changing the system indicators.
The performance index can be reduced to an acceptable level, and the system can operate safely and stably to complete its functions.
