The aim of this research paper is to propose an alternative but possible practical solution to basic key and common security threats such as overloading (Flooding Attacks) and their associated risks to a typical industrial automation system. For this purpose, countermeasures that can be directly implemented in end points regardless of any specific hardware or deployment platform are considered here. These proposed solutions include developing new control systems that can defend associated industrial automation processes and themselves against such attacks, i.e., identifying and building a defense mechanism in control algorithm, and hence named self-defending control strategies. For demonstration an example of such control algorithms was developed and simulation results are presented.

Microgrids are characterized as weak systems with poor power quality due to significant variations in frequency and/or voltage that can occur during sudden changes in load demand. This problem is exacerbated in cases where one of the power sources is tied to the microgrid through a grid-interactive inverter which is designed to trip when deviations in frequency and voltage exceed well-defined thresholds that are specified by interconnection standards. Numerous solutions with variable complexity are proposed in the literature, including the integration of battery storage systems. This paper presents a simple alternative method that does not require any hardware nor software for solving the inverter tripping problem. Field experiments show that using an advanced inverter with controllable voltage and frequency ride-through capability eliminates the inverter disconnection under any condition, thus improving system performance and reliability.

This work deals with analysis of the linear predictive coefficients with respect to their use for acoustic gunshot detection. First, coefficient stability was observed when changing length and position of an analysed signal frame. Then, the optimal prediction order was investigated. Finally, false alarms and correct gunshot detections were tested for various numbers of coefficients. The best experimental results achieved were 8.6% false alarm rate and 88% gunshot detection rate.

In this paper, a three-port, galvanic isolated, bidirectional power converter is proposed to control the power flow between the main dc buses, low voltage loads and energy storage unit on a generic airplane. A simplified model of the converter is presented to explain the control strategies design procedure. Simulations of the developed closed-loop controller that manages the energy exchange in different operating conditions are provided. Finally, a laboratory prototype based on GaN power devices is described and basic experimental results are presented.

This paper deals with the stability analysis of the well-known Adaptive Full-Order Observer for the speed estimation of induction motor drive in a motoring and regenerating mode, under motor parameter mismatch. The influence of the identification errors of the stator and rotor resistance and magnetizing inductance on unstable operating points regions of the estimator with the modified adaptation algorithm for the regenerating mode are discussed. The changes of stability regions and torque-speed characteristics of the drive under parameter uncertainties are shown and discussed in the paper for the observer with the speed adaptation law modified by the shift angle between the stator current error and rotor flux vectors. Simulation and experimental results confirming the theoretical analysis are presented.

The actuation system of an aircraft relies heavily on hydraulic actuation. In order to improve the reliability of the system while improving the power density, researchers have investigated the possibility to increase the penetration of electric system. In this scenario, the electrical power distribution system (EPDS) becomes very important This paper proposes an architecture of the EPDS based on dual active bridge converters, virtual resistors are used to share the power and to handle faults. Simulation results show the good behavior of the EPDS, that can withstand faults in the buses and still supply the critical loads.

This paper presents the development of a self-tuning digital controller for DC motor applications, specifically designed using hardware/software co-design techniques. Two tuning structures are investigated and then implemented, both reliant on a compass direct search algorithm. The developed structures overcome many of the typical limitations of classical self-tuning methods; such as computation complexity, simplicity of adaptation, and ease of real-time tuning. The self-tuning processes are based on measuring the closed loop impulse response by injecting an excitation signal and comparing the measured signal with the desired ideal impulse response. Optimal PID parameters are achieved once the measured and the desired impulse response are matched. Special focus is given on rapid implementation of the presented on-line tuning mechanism for the digital PID controller using the National Instruments-RIO architecture and LabVIEW-FPGA design tools. Validation of the self-tuning and hardware/software co-design approach is demonstrated on an experimental position controlled DC motor drive application.

In this paper, we propose a completed hardware design for the robotic cane, which was only demonstrated by simulation in [1], and stops as an idea in [2]. Besides, the controller of the robotic cane is verified by good experiment results like very small variations of the angle of the robotic cane, the robotic cane can stand in balance without any external forces, and it responds fast to external forces from users to return the balance point. To design the controller, the Lie Algebra (LA) method is used to linearize the nonlinear system of the inverted pendulum and find the control parameters. Besides, the Linear Quadratic Regulator (LQR) method is applied to the robotic cane to prove that the performance of LA method is better.

Rehabiliation robotics combined with video game technology provides a means of assisting in the rehabilitation of patients with neuromuscular disorders by performing various facilitation movements. The current work presents ReHabGame, a serious game using a fusion of implemented technologies that can be easily used by patients and therapists to assess and enhance sensorimotor performance and also increase the activities in the daily lives of patients. The game allows a player to control avatar movements through a Kinect Xbox, Myo armband and rudder foot pedal, and involves a series of reach-grasp-collect tasks whose difficulty levels are learnt by a fuzzy interface. The orientation, angular velocity, head and spine tilts and other data generated by the player are monitored and saved, whilst the task completion is calculated by solving an inverse kinematics algorithm which orientates the upper limb joints of the avatar. The different values in upper body quantities of movement provide fuzzy input from which crisp output is determined and used to generate an appropriate subsequent rehabilitation game level. The system can thus provide personalised, autonomously-learnt rehabilitation programmes for patients with neuromuscular disorders with superior predictions to guide the development of improved clinical protocols compared to traditional theraputic activities.

Recent advances in information technologies and artificial intelligence are enabling the creation of intelligent and highly reconfigurable factories which will lead to unprecedented production development. The notion of Cyber-Physical Production System (CPPS), denoting a system where mechatronic components are coupled to a smart logical entity that enables these factory units to interact in an adaptive way, has been presented as one of the cornerstones of what is perceived to be the 4th Industrial Revolution. However, more than two decades of research have shown that such a vision is not as new as recent programmes suggest and that certain developments are only now reaching a maturity stage that renders them usable with limitations. These are due to a set of persistent design challenges that undermine their acceptance along with the fact that the preconditions for operating such systems globally are far from being satisfied. This paper provides an integrated, clear and critical view on pending design issues that still need to be satisfied. In this context, the paper concentrates on the conceptual and technical design barriers that relate to the development of cyber-physical production components and their operation in the context of a CPPS.
