This paper presents the introduction to the Human-in-the-loop issue connected to the concept of the Cyber-physical systems (CPS). In this context, the brief overview of CPS is provided, with emphasis on the role of human in cooperation with CPS. Such systems are often called Human-in-the-Loop Cyber-Physical systems (HiLCPSs). The following part of this paper brings the short background of HiLCPS and approaches for human performance assessment. The last part deals with example of human performance assessment based on the real data. For these purposes, several approaches is used, e.g. evaluation of measured human responses or evaluation of human dynamic properties based on the modelling of human behavior. The input data was collected using measurements with real human/pilots. Due to many realized tests with pilots in the different stage of training, there is statistically relatively significant set of input data. © 2018

作者： Jirgl, M. Bradac, Z. Havlikova, M. Department of Control and Instrumentation Faculty of Electrical Engineering and Communication Brno University of Technology Technicka 3082/12 Brno616 00 Czech Republic

This paper deals with an interaction between human and controlled element called MMS (Man-Machine systems) and presents a methodology of measurements, evaluation and modelling of human behavior using modern simulation and computation technologies and statistical methods. For this purpose, mathematical models of human behavior must be described. Based on these models can be evaluated actual state of human abilities in terms of dynamic properties, e.g. reaction delay, adaption on controlled element ability, etc. These abilities expressed by the model parameters and their changes in time are observed. The nature of this approach is data acquisition and processing from a real environment. This data are obtained from flight simulator at Brno University of Defense where two sets of test measurements with real pilots were realized. © 2016

Driver's fatigue is a common source of traffic accidents. In this paper, a methodology is developed to measure and evaluate dynamic behavior of the driver, determine the differences between the behavior of unwearied and fatigued driver and to develop a mechanism to detect possible dangerous situations. The method for fatigue monitoring is based on monitoring and analyzes of the driver's trajectories. Position of the vehicle on the road was continuously monitored by a camera and the lateral position was evaluated from the designed reference guide line. Sets of test drives were performed within 24 hours on a driving simulator. © 2016

The goal of this paper is to present the possibilities of energy harvesting using the modern components called energy management systems. These circuits are integral parts of modern energy harvesting systems and are responsible for management of power supply, energy storage and flow of energy between individual components. This paper focuses on the E-PEAS AEM10940 circuit. It is a small device usable for low power embedded systems. Thus, its basic characteristic and properties obtained by repeated short-term and long-term measurements are presented and evaluated. © 2018

This paper presents the classification of metals materials by application of Hall Effect sensor based on the eddy current method with non-destructive testing. The electromagnetic field was generated by winding an SWG 22 wire onto the ferrite core to create a solenoid. Two measurement systems are used. One uses a Pure DC supply as the excitation voltage of the electromagnetic field of the Hall Effect sensor system;while the other uses a combination of AC and DC supply, which is amplified through an integrated Class-A amplifier circuit, as the excitation voltage. Three different metal samples, namely, steel, aluminum and stainless steel were used as specimen. Current test conducted to determine the suitable current level revealed that a 0.8 A current is safe to allow tests to be conducted. Results show that the Combined DC system is capable to classify conductive materials, where the Pure DC system lacks in this functionality. The Output voltage of Hall Effect sensor to test with steel, aluminum and stainless steel is 4.68 V, 1.74 V and 3.63 V, respectively. Furthermore, the use of the Combined DC system enables aluminum thickness to be distinguished. The tolerance of the system measuring the materials when using the Pure DC and Combined DC are pm 0.0697% and pm 0.58530% respectively. © 2018 The Society of Instrument and control Enginners - SICE.

Input shapers with time delays have proved useful in many applications related to controls for various flexible devices, for example flexible manipulators and cranes. In the paper, modifications of classical signal shapers ZV (zero vibration) and ZVD (zero vibration derivative) that use uniformly distributed delays instead of lumped delays are proposed. The shaper parameters, i.e. gains and time delays, are determined using spectral approach. The objective is to compensate the undesired oscillatory couple of system poles by the dominant couple of shaper zeros. Next, the spectral and frequency features as well as robustness issues are investigated. In all these aspects, the shapers with distributed delays show better characteristics compared to classical signal shapers. The theoretical results are verified on a laboratory crane system. © 2012 IFAC.

In this paper, a dynamic co-evolution compact genetic algorithm (DCCGA) is proposed for flexible flow shop scheduling problem (FFSP) to minimize the total earliness and tardiness (E/T) penalties. In this new algorithm, a dynamic co-evolution mechanism containing two probabilistic models and a best individual inheritance strategy are integrated into the compact genetic algorithm (CGA). For improving the stability of the evolutionary trend in the evolution processes, the diversity of evolution trend and the convergence speed. Lastly, the experimental results show that, DCCGA outperforms CGA by 11.74% on the problem we study. © 2015

Active disturbance rejection control of a parallel manipulator with self learning algorithm for a pulsating trajectory tracking task

引用

Scientia Iranica 2012年第1期19卷 132-141页

A novel and robust intelligent scheme is proposed to control a highly non-linear 3-RRR (revolute-revolute-revolute) planar parallel robotic manipulator, via an Active Force control (AFC) strategy that is embedded into the classic Proportional-Integral-Derivative (PID) control loop. A PID-type Iterative Learning (IL) algorithm, with randomized initial conditions, is incorporated into the AFC loop to approximate the estimated inertia matrices of the manipulator adaptively while the manipulator is tracking a prescribed pulsating trajectory in the presence of harmonic disturbances. The IL algorithm employs a stopping criterion, which is based on tracking error, to stop the learning process when the desired error goal of the system is reached, to signify a favorable controlled condition. A numerical simulation study was performed to verify the robustness of the proposed methodology in rejecting disturbances, based on given loading and operating environments. The results of the study reveal the superiority of the proposed system, in terms of its excellent tracking performance compared to the AFC, with crude approximation techniques, and Proportional-Integral-Derivative (PID) counterparts. © 2012 Sharif University of Technology.
