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....
Based on the developed nonlinear dynamic equations of a quadrotor (named as Qball-X4) UAV (Unmanned Aerial Vehicle), attitude and trajectory tracking control designs based on an inner/outer loop control structure has been proposed in this paper. Feedback linearization is designed to control the attitude stability in inner loop, traditional PID is designed to follow trajectory in accordance with pre-planned...
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...
In this paper, a fault tolerant control method based on the parametric estimation is presented and applied to the air path system of a diesel engine. This method uses directly the results of a parametric estimation of the system which is nonlinear and whose state variables and parameters are strongly coupled. Our goal is to adapt an Unconstrained Nonlinear Continuous-time Generalized Predictive Control...
Nowadays, fault diagnosis systems design should have into account the distribution and complexity of the process and must be able to cooperate and communicate with other systems to achieve satisfactory performance. To this end a new agent based fault detection system for networked control process is proposed in this paper. A hybrid architecture based on horizontal layers as fault detection (FD) agents...
