Özet:

 

Fault detection and compensation play a key role in   enhancing the high demand for performance and security in technological   systems. This paper proposes an active fault-tolerant control scheme that   detects and compensates for actuator faults in a 4-tank system benchmark.   The faults are modeled as a drastic gain loss in actuators (pumps), which   could lead to a large loss in the nominal performance. The model-based   approach uses a recursive least squares parameter estimation algorithm to   form a fault detection and diagnosis subsystem and utilizes a parametric   eigenstructure assignment method to reconfigure the state feedback   controller. The designed controller is simulated for the nonlinear system,   and the results demonstrate promising performance increases in faulty cases   in comparison with the nonfault-tolerant controller.
