Linear motors have many advantages in compare with rotary motors due to directly creating linear motion without gears or belts,… It is hard to apply the online model predictive controller for electro-mechanism systems with input, output and state constraints because it requires the good ability in calculations of microcontroller and the nonlinear property of these models. In this paper, the exact linearization is applied to obtain the corresponding linear model and we propose the offline model predictive control law based on multi-parametric programming (MPP) for permanent magnet linear synchronous motors (PMLSM) to remarkably reduce amount of calculation. Thus, it is convenient for embedding the control law into microcontroller. Several simulation results show the ability of the proposed method in this paper.

In this paper, we analyze the variation tolerance of time-shared Twin Memristor Crossbar (TMC) for various inter-correlation and intra-correlation parameters. Here the percentage variation in memristance is increased from 0% to 40%. The statistical analysis performed here indicates the original TMC and the time-shared TMC show almost the same tolerance to memristance variation when the variation of all memristors in one array are assumed random, referred to as intra-array correlation is zero. However, when the intra-array correlation becomes as high as 1, in other words, variations of all memristors in the same array are correlated each other, the time-shared TMC shows better recognition rate by 5% on average, compared to the original TMC. From the statistical simulation results, we can expect the time-shared TMC has better variation-tolerance than the original TMC, in pattern matching application.

The paper covers the central issues of data warehousing modeling including: (1) formulating the data representation, (2) establishing the foundations of storage structure, (3) proposing corresponding architecture allowing to store, update and manage data. Consequently, two levels are considered in this paper to address the above mentioned research axes. First, at a theoretical level, the objective is to introduce novel and practical contributions in the area of textual document-based plagiarism system. The chosen approach is proposed to collect, analysis and store textual dataset. Secondly, at an implementation level, the paper focuses on the platform for processing the data, calling to modeling exhibits promising capabilities such as support for real-time, new sources of data, and self-service capabilities. The real application is performed in Vietnamese text-based document by conducting documents containing final reports/assignments, dissertations of master/Ph.D and research scientific papers applied for the University of Danang. The contribution of the paper is not only provide values to all researchers, educators and students in the university of Danang systems but also be considered as seminal work to develop plagiarism in our further next investigation of building a big-data warehouse severing for a automatic duplicate system.

This paper presents an experimental method to measure the thickness of oil film of a connecting-rod big end bearing. A specific experimental device and a connecting-rod model of photo-elastic material are used to determine the load diagram and to measure the oil film thickness. The method consists in taking two images of a solid, before and after deformation. The surface of the connecting rod is painted with dark spots. Reference images, before deformations, and deformed images are recorded by using a CCD camera and imaging software at different angular positions of the crankshaft. We have developed a technique to measure the thickness of the film by the correlation method of digital images. The measurements of oil film thickness according to the crank angle corresponding with the load diagram and are confirmed by electrohydrodynamic lubrication. The thicknesses of film thus measured can then be compared with the thicknesses given by the numerical calculations.

In recent years, the use of biofuels in the conventional diesel fuel injection system has been interested by the scientists, fuel producers as well as consumers. However, there has a few of using biodiesel research on Common Rail (CR) diesel engine. This paper descripts a combustion model of a CR multi-injection diesel engine using blends of palm oil derived biodiesel and diesel. The engine combustion parameters such as peak pressure, heat release rate and ignition delay were measured and computed, the mass fraction burn at 50% (MFB50) was also investigated in this paper.

This paper presents a DSP- and DC-DC converter- based photovoltaic (PV) emulator which can simulate the output characteristic of a real PV module. The control mechanism is a combination of the current mode controller with a modified look up table of PV module characteristic which generates the reference current based on the measurement of converter output voltage and current. A prototype of the PV emulator is built to validate the proposed control method. The experimental results shows that the designed PV emulator has a fast transient response as well as steady state operating points well fitted with theoretical characteristic.

This paper presents an adaptive backstepping hierarchical sliding mode control algorithm for uncertain 3D overhead crane model. Backstepping sliding mode is constructed based on hierarchical structure to guarantee tracking for trolley and anti-swing for load. Neural network is adopted to approximate the uncertain terms. The disadvantage of sliding mode control is fixed by changing signum function to saturation function. The purposes of this paper are to use RBF neural network to approximate nonlinear function of crane, design hierarchical sliding mode controller based on Lyapunov theory.

Robotic systems are widely used in the manufacturing industries to improve high quality products. When a fault occurs in manipulator, the faulty robot operates in abnormal condition, which causes insecurity for devices and human. In general, the dynamic of residual vector consists of fault information. In order to evaluate the residual vector, data-driven technique based on statistical theory is used. This paper presents a method by using the combination between the residual vector and data-driven solution for detecting and isolating actuator, sensor faults in robot manipulator. To achieve the accurate and reliable detection and isolation of sensor and actuator faults, the threshold is proposed to combine with generalized momenta. Simulation results are realized to show the performance of proposed method.

Bilateral teleoperation is a robotic system helping humans to work with the remote environment through a dual robot which includes a local robot and a remote robot operating with considerable time delays. In order to overcome this obstacle, beside the proposed wave variables and scattering approaches [1], [2], the conventional methods without wave variables has been pointed out in [3], [4] with constant time delay. In this paper, we propose a new adaptive control law based on Lyapunov's direct method to address time varying delays and position synchronization between two robots. In addition, force control was considered to guarantee tracking position error which converges to zero under humans and environment disturbances. The validity of them is based on theory and the good performance of the proposed controller shown in simulation results.
