Significant research has been carried out over the past three decades in the area of fault tolerant control. Most methods available in the chemical engineering literature are capable of detecting, identifying, estimating and accommodating faults for nonlinear processes with continuous states without state dependent and controlled switching. This work is aimed at developing a method for diagnosing...
In this paper, an approach to design an Admissible Model Matching (AMM) Fault Tolerant Control (FTC) based on Linear Parameter Varying (LPV) techniques is proposed. The main contribution of the proposed approach consists in the on-line reconfiguration of the controller based on the use of LPV gain-scheduling techniques that allow to take into account changes in the system parameters due to changes...
This paper proposes a fault-tolerant control strategy for a nonlinear electro-hydraulic system. The fault-tolerant control scheme consists a fault diagnosis system and a reconfigurable controller. The fault diagnosis system is designed based on differential-geometric approach and is robust to system disturbance. Adaptive backstepping method is utilized for realizing the reconfigurable controller....
Internal Model Control (IMC) has been extended recently to a fault-tolerant IMC scheme (FTIMC), which ensures that the main IMC properties like stability, robustness and setpoint tracking are retained if faults occur. This paper proposes a new type of IMC controller for input-affine systems with input-saturation, which is based on a systematic analysis of the demands on the IMC filter, the construction...
