Today, the demand for continuous monitoring of valuable or safety critical equipment is increasing in many industrial applications due to safety and economical requirements. Therefore, reliable in-situ measurement techniques are required for instance in Structural Health Monitoring (SHM) as well as process monitoring and control. Here, current challenges are related to the processing of sensor data with a high data rate and low latency. In particular, measurement and analyses of Acoustic Emission (AE) are widely used for passive, in-situ inspection. Advantages of AE are related to its sensitivity to different micro-mechanical mechanisms on the material level. However, online processing of AE waveforms is computationally demanding. The related equipment is typically bulky, expensive, and not well suited for permanent installation. The contribution of this paper is the development of a Field Programmable Gate Array (FPGA)-based measurement system using ZedBoard devlopment kit with Zynq-7000 system on chip for embedded implementation of suitable online processing algorithms. This platform comprises a dual-core Advanced Reduced Instruction Set Computer Machine (ARM) architecture running a Linux operating system and FPGA fabric. A FPGA-based hardware implementation of the discrete wavelet transform is realized to accelerate processing the AE measurements. Key features of the system are low cost, small form factor, and low energy consumption, which makes it suitable to serve as field-deployed measurement and control device. For verification of the functionality, a novel automatically realized adjustment of the working distance during pulsed laser ablation in liquids is established as an example. A sample rate of 5 MHz is achieved at 16 bit resolution.

“…As a tight integrated system, cyber-physical systems are composed of physical elements (including controllers, sensors, actuators, plants) and cyber networks for accurate sensing, ubiquitous computation, efficient communication, effective control [1][2][3] . The real application communities of CPSs cover transportation [4,5] , health monitoring [6,7] , manufacture [8,9] , smart gird [10] , aerospace system [11] , and so on. The connection to the internet in CPSs renders it is more vulnerable to malicious instructions and attacks.…”

An adaptive resilient control is concerned for a class of cyber-physical systems(CPSs) in presence of stealthy false data injection attack s in sensor networks and unknown strict-feedback nonlinear dynamics. As the sensors are attacked by ill-disposed hackers, the exactly measured state information is unavailable for state feedback control. After theory ratiocinations, the initial issue of false data injection attacks is transformed into nonlinear uncertainty dynamics and unknown control directions at the last step. At each step in the recursive backstepping control, extended state observers (ESOs) in active disturbance rejection control(ADRC) are investigated to approximate the lumped system uncertainties. Specially, the Nussbaum functions are introduced at the last step in the adaptive control. All the closed-loop signals are proved to be semi-globally uniformly ultimately bounded by Lyapunov theory. Finally, numerical simulations verify that the proposed control can afford favorable stabilization performance and counter false data injection attack.

<p>Existen distintos dispositivos capaces de discriminar el ruido óptico y optoelectrónico, sin embargo, el costo de su implementación y mantenimiento resulta costoso. Este trabajo examina la posibilidad de integrar digitalmente filtros de respuesta finita al impulso (en inglés, FIR; Finite Impulse Response) al transductor de un sistema OSS para obtener un mejor rendimiento en un ambiente real de operación. En este trabajo se propone la evaluación de la implementación de distintos filtros FIR en diferentes transductores fotosensores como lo son el resistor dependiente de luz (en inglés, LDR; Light-Dependent Resistor) y el diodo emisor de luz (en inglés, LED; Light-Emitting Diode).</p>
