“…Abbaspour et al introduced a neural network (NN) fault detection design for detection of abrupt faults in actuators and sensor of the control systems. They used extended Kalman filter to improve the NN ability in detection of faults [6]. A neural observer approach for detection of FDI attack is introduced in [7].…”

Networked Control Systems (NCSs) have been implemented in several different industries. The integration with advanced communication networks and computing techniques allows for the enhancement of efficiency of industrial control systems. Despite all the advantages that NCSs bring to industry, they remain at risk to a spectrum of physical and cyber-attacks. In this paper, we elaborate on security vulnerabilities of NCSs, and examine how these vulnerabilities may be exploited when attacks occur. A general model of NCS designed with three different controllers, i.e., proportional-integral-derivative (PID) controllers, Model Predictive control (MPC) and Emotional Learning Controller (ELC) are studied. Then three different types of attacks are applied to evaluate the system performance. For the case study, a networked pacemaker system using the Zeeman nonlinear heart model (ZHM) as the plant combined with the above-mentioned controllers to test the system performance when under attacks. The results show that with Emotional Learning Controller (ELC), the pacemaker is able to track the ECG signal with high fidelity even under different attack scenarios.

“…On the other side, actuator faults occurrence may cause fatal behavior of the closed-loop system; see, for instance, [17][18][19]. Moreover, and to increase the reliability and safety of sophisticate controlled systems, the design of actuator fault robust control and fault detection systems are an important challenger [1,18,19].…”

“…Moreover, and to increase the reliability and safety of sophisticate controlled systems, the design of actuator fault robust control and fault detection systems are an important challenger [1,18,19]. Motivated by the event-driven control design of self sampled-data design philosophy, and by employing our own design, the main objective of this paper is to grant an auto-sampling event-driven robust control design against actuator failures and a fault detection invention system applied to mechanical systems.…”

This paper presents a recent self-sampled-data control algorithm applied to nonlinear systems with actuator failures. Our approach uses the linear model of a given nonlinear system, and based on a granted actuator fault observer method, an asynchronous sampled-data fault compensator controller is then formulated. The proposed sampling rule is realized by using an event-detector monitoring signal invention. On this way, the sampled rate is self governed and asynchronous by nature. Hence, our contribution is twofold. Fist, a new auto-generated non-uniform sampled-data mechanism is stated. Second, we grant an event-triggered control law with actuator failure observation and compensation. Our findings are completely supported by employing Lyapunov's theory. Finally, according to our numerical experiments applied to an undamped torsional pendulum, our design is able to detect a failure in the actuator device and it can stabilize the undamped torsional pendulum system presenting better performance in comparison to its open-loop deployment.

“…A small electric antenna can be defined as an antenna which possesses geometrical dimension that is small in comparison to the wavelength of the electromagnetic fields they radiate [1,2]. These antennas have various applications in unmanned vehicles [3,4,5], radars [6], and wireless communication [7,8] which motivate researchers to develop these antennas based on their needs. Metamaterial structures which are first developed by V. G. Veselago in 1967 provide electromagnetic properties that do not exist in nature and include negative index of refraction, negative permittivity, or negative permeability [9].…”

In this work, a compact and broadband and planar monopole antenna consists of one unit cell of epsilon negative transmission line (ENG TL) is proposed. A disc-shaped monopole antenna is implemented at 2.45 GHz resonance frequency for 2.4 GHz applications. A 50 Ω microstrip line is used as a feedline and element of the antenna has 0.1λ 0 of diameter. The size of the antenna is reduced to 0.32λ 0 × 0.32λ 0 , and the -10 dB fractional bandwidth is improved to 12.8% due to using metamaterial transmission line. Prototype antenna is fabricated and tested, and the measured results are compared to the simulated results using Ansoft HFSS.
