In many applications it is desirable to use a decentralised control strategy, in which multiple sensor-actuator pairs are utilised to control the response of a structure. This avoids the need for connections between multiple sensors and actuators and allows the system to be easily scaled to different applications. However, because the individual control loops, consisting of a single sensor-actu...

Robot frame compliance has a large negative effect on the global accuracy of the system when large external forces/torques are exerted. This phenomenon is particularly problematic in applications where the robot is required to achieve ultra-high (micron level) accuracy under very large external loads, e.g. in biomechanical testing and high precision machining. To ensure the positioning accuracy...

We study the problem of actuator and sensor placement in a linear advection partial differential equation (PDE). The problem is motivated by its application to actuator and sensor placement in building systems for the control and detection of a scalar quantity such as temperature and contaminants. We propose a gramian based approach to the problem of actuator and sensor placement. The special s...

We propose a new granular crystal sensor and actuator suite based on highly nonlinear solitary waves to offer a compact, inexpensive, and reliable diagnostic instrument for biomedical applications. A granular crystal sensor/actuator composed of tightly packed elastic particles is assembled to generate and retain self-reinforcing, nondispersive diagnostic solitary waves. Via direct contact, this...

In this paper the explicit (closed form) solutions to several application-motivated parabolic problems are presented. The boundary stabilization problem is converted to a problem of solving a specific linear hyperbolic partial differential equation (PDE). This PDE is then solved for several particular cases. Closed loop solutions to the original parabolic problem are also found explicitly. Outp...

This paper presents a new approach to robustly track a robot’s location in indoor environments using a partially observable Markov model. This model is constructed from topological representation of the environment, plus actuator an sensor characteristics. The system takes into account various sources of uncertainty to maintain a probability distribution over all possible locations of the robot...

Recent research efforts are considering the problem of performing control of dynamical systems over wireless sensor and actuator networks. However, existing results lack an experimental evaluation in real platforms. In this demonstration an inverted pendulum system is controlled over an IEEE 802.15.4 wireless sensor and actuator network. This platform can evaluate several sensor networks and co...

in this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for v47/660kw wind turbine operated in manjil wind farm, gilan province, iran. according to the acquired data from iran wind turbine industry, common faults of the wind turbine such as sensor fault...
