Possible faults existing in electronic diesel fuel injection control (EDC) systems include rack deformation, solenoid valve failure, and rack-travel sensor malfunction. Among these problems, the solenoid failure is the most likely to occur for in-use diesel engines. This paper focuses on developing the algorithm that can clearly classify the usability of a solenoid valve without disassembling t...

The problem of reliable robust H∞ tracking control for a class of Lur’e singular systems with parameter uncertainties is studied. The uncertainty is assumed to be convex polytopic. A practical and general failure model of actuator and sensor is considered. Some sufficient conditions about reliable robust H∞ tracking control are presented for the case of actuator and sensor failures in terms of ...

In this paper, a novel resource management approach is presented for publish-subscribe middleware for sensor/actuator networks. The resource management was designed with the possibility to add non-functional requirements at runtime to subscription messages. This approach allows utilizing service level agreements that can then be employed in order to guarantee a certain quality of service or to ...

Fault detection and isolation (FDI) logic plays a crucial role in enhancing the safety and reliability, and reducing the operating cost of aircraft propulsion systems. However, it is a challenging problem achieving the FDI task with high reliability. For this purpose, various approaches have been proposed in the literature. In an on-line engine fault diagnoses, two tasks may use Kalman filter t...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

Sensors and actuators are critical components of several embedded systems (ES) and can trigger the incidence of catastrophic events [1-3]. Sensor and actuator faults detection is difficult [2, 3] and impacts critically the system performance. While integrating sensors and actuators with the rest of (sub) system, there is a need to identify all failure modes and rectify them. Several researchers...

In this paper, the problem of configuration selection i.e. sensor/actuator placement for piecewise affine (PWA) systems subject to both sensor and actuator faults is considered. A method is proposed that provides a tool for the design phase to decide about the optimal placement of sensor/actuators where the reconfigurability of the system subject to sensor and actuator faults is also taken into...

In this paper, a robust adaptive actuator failure compensation control scheme is proposed for a class of multi input multi output linear systems with unknown time-varying state delay and in the presence of unknown actuator failures and external disturbance. The adaptive controller structure is designed based on the SPR-Lyapunov approach to achieve the control objective under the specific assump...

Thepresent paper discusses active vibration control of a cantilever beam subjected to random base excitation. The smart materials used are piezoelectric patches for both as sensor and actuator, and actuation based on the surface strains. Finite element model of the smart beam is obtained using Euler-Bernoulli formulation. Positive Position Feedback (PPF) controller is proposed for active dampin...
