To model the cooperative behavior under the realistic world, we put forward a high clustering network model with the property of adjustable power-law, and analyze the evolution of the prisoner dilemma game on this improved HK network model. Using simulation experiments, we investigate the effect of high clustering property of this network on the cooperative behavior. Extensive simulations indicate...
This paper addresses the design of a path-following using a sampled-data Model Predictive Control (MPC) approach for a fixed-wing Unmanned Aerial Vehicle (UAV). In path-following, the motion task consists in steering the vehicle towards a given desired geometric path and make it follow along the path with an assigned speed profile. To this end, we propose an MPC controller that will generate desired...
In this project, we developed a chess play system based on Kinect vision sensor, which recognizes different hand gestures as a command and sends these commands to V-REP robotic simulation tool. Delta type robot will play chess according to the commands sent via vision software. In our system, we have tested for 2 different chess opening scenarios and DOF checking mode scenario, then we obtained results...
In this paper, the reliability of transient simulation results of uni-traveling-carrier photodiodes (UTC-PDs) is demonstrated by compared with experimental and reported simulation results, when the parameters of drift-diffusion model are set correctly.
Aiming at the speed regulation system of permanent magnet synchronous motor (PMSM), the research and analysis of PMSM speed regulating system are made. Based on the finite time control technique, a finite time controller is designed in this paper. This design utilizes the error between the output of the speed and the reference speed, to be controlled by a finite time controller to obtain the q-axis...
With the development of deep space exploration, the requirements of accuracy and real time for navigation services become higher, so that the traditional ground based network can hardly meet the user's needs. And the accuracy of existing autonomous navigation method, such as celestial navigation, cannot meet the requirement either. In order to improve the performance of autonomous navigation for deep...
A stratospheric airship is difficult to achieve long duration flight at about 20km altitude at mid or low latitudes, where it endures pressure changes due to the heating and cooling of the day-night cycle. In order to overcome these difficulties, this paper proposed a novel stratospheric airship based on triple-gasbag principle, and investigated its static and dynamic behavior. Firstly, this paper...
In this paper, a robust control method is proposed for a class of fractional-order nonlinear system with unknown system parameter based on Lyapunov direct method. The Caputo definition is used to describe the fractional-order dynamic system. The controller is simple and enables asymptotically stability to be achieved without the computation of the conditional Lyapunov exponents. Finally, simulation...
This study presents a decoupled sliding mode controller for an inverted pendulum on a cart. The sliding mode control is a special type of variable structure control and it is applicable to the systems represented in the canonical form. For the systems which are not represented by the canonical form such as the inverted pendulum, the decoupled form of the sliding mode controller can be used. In this...

The article addresses specific issues of the automated heating systems for non-residential buildings, which aim to ensure thermal comfort with low energy consumption. The specialized automatic system maintains constant the indoor temperature when the heat input in building equals the heat loss through the building envelope. The specialized automatic system consists of several subsystems. The model...
In this article is modeled, with the help of Simulink, the automatic system that controls the thermal agent temperature in a non-residential building chosen for study. It describes how the model has been drawn for the subsystem entitled HEATED SPACE in the building. There were used mathematical relationships which show how the indoor temperature is changing, depending on the heat input in building...
Discrete-event simulation (DES) is a developed technology used to model manufacturing and service systems. However, although the importance of modelling people in a DES has been recognised, there is little guidance on how this can be achieved in practice. The results from a literature review were used in order to identify examples of the use of DES to model people. Each article was examined in order...
In recent years, the Z-bending process was rarely investigated, especially for the asymmetrical Z-shape bending process. This causes the lacks of understanding on bending mechanism and spring-back characteristics and results in the difficulty in die design and process control for the spring-back characteristics. In the present research, therefore, the wiping asymmetrical Z-bending process was examined...
We have investigated dynamic characteristics of ferroelectric Hf02 (FE-Hf02) by considering multiple domain (MD) and linear domain-domain interaction. By using the calibrated MD model, experimental dynamic responses of FE-HfO2 can precisely reproduced, for the first time. Input voltage amplitude (Vin) and external resistance (R) dependences of dynamic responses in FE-Hfö2 revealed that dynamic term...
The storage of the quantum bit, also called “qubit”, is a critical issue in the field of quantum information. As a promising candidate of being a quantum device, semiconductor quantum dots (QDs) are expected to play a central role in quantum information networks. Therefore, the study of quantum information storage in the QDs is really important. In this work, we employ the quantum master equation...
Locomotives are equipped with slip controllers to limit a value of a wheel slip velocity and conducive to reach required locomotive tractive effort. The slip control methods are developed for tenths years, and the methods are based on several principles. Progressive methods determine an adhesion-slip characteristic slope. This method requires knowledge of an adhesion coefficient value or an adhesion...
Currently the special algorithms are used to determinate an initial position of rotor angle of the permanent magnet synchronous drives. This is especially important for providing of smooth load at the electric drive starting, for example, for gearless elevator hoist drive. For this the position sensors are used in simple electrical drives, but system cost is increased. Paper describes a developed...
Finite difference time domain (FDTD) method is widely used to understand and interpret results of Ground penetrating radars (GPR). Simulation studies using FDTD on response of buried features to GPR is a standard practice. However, quantification of these simulated GPR response, which is required for application to real life problems, is not common. In the present work, several scenarios of pipe buried...
