Actuator and sensor faults can cause poor performance or even instability in dynamic systems. In flight control systems for aircraft and spacecraft, such faults can lead to loss of control and serious incidents. Therefore, rapid detection and identification of actuator and sensor faults is important for enhancing flight safety. One approach to fault detection and identification (FDI) in actuato...

A systematic method is developed for determining an output matrix C for a given matrix pair (A; B) such that the resulting linear system characterized by the matrix triple (A; B; C) has the pre-speci2ed system structural properties, such as the 2nite and in2nite zero structure and the invertibility structures. Since the matrix C describes the locations of the sensors, the procedure of choosing ...

In a world of unknown, touch modality is a key avenue for environments exploration. Implementation of such modality in mobile robot has been a major challenge for many research teams. Recently, several artificial whisker systems have been studied as promising tactile sensor. One key to the whisker’s functionality is its sensor system. Our laboratory recently synthesized new electroactive polyme...

Sensor-actuator networks require sharing of actuators across multiple applications. Here, simple device arbitration is not enough because actuators have lasting (or irreversible) effects on their environment. For example, actuating a heater not only affects the internal program state of the controlling application, but the nearby temperature as well. This change in external environment often ha...

This paper features the modeling and design of a Robust Decentralized Fast Output Sampling (RDFOS) Feedback control technique for the active vibration control of a smart flexible multimodel Euler-Bernoulli cantilever beams for a multivariable (MIMO) case by retaining the first 6 vibratory modes. The beam structure is modeled in state space form using the concept of piezoelectric theory, the Eul...

The aim of this work is to optimise the vibration of the plate with the help of Adaptive neuro-fuzzy inference system (ANFIS) controller. The contribution of piezoelectric sensor and actuator layers on the mass and stiffness of the plate is considered. As the plate is square so we get total 64 squares. To validate the present code, frequency response has been compared with exact solution as wel...

This work presents the design and implementation of a wireless home monitoring and automation system consisting of wireless sensor/actuator nodes, wireless camera, and a home server. The low-cost wireless sensor/actuator node features temperature, light intensity and motion sensors, and actuator driver circuits for the control of motors, heaters, and lights. Server and client programs used to m...

Robotic systems are capable of complex behavior by sequencing simpler skills called primitives (Voyles, Morrow, & Khosla 1997). A primitive is a sensor/actuator mapping robust enough to perform appropriately in various situations. Programming one primitive can be tedious and requires an accurate translation of human knowledge to machine code. Once a sufficient set of primitives is coded, the us...
