This paper studies the system of Electric-field Coupled Power Transfer (ECPT) based on the E-class amplifier topology. An CLC-S-compensated circuit topology is applied at the primary side to resonate with the power transmitting plates. The voltage gain model is presented with the help of the impedance transformation principle. There are three system parameters (the load quality factor Q, the normalized...
A Proportional-integral-derivative (PID) control of highly nonlinear and multivariable two stage pendulum is presented. The aim is to settle cart at desired position within 4 seconds while both the pendulums are inclined vertically upwards. Three PID controllers were separately designed for control of each subsystem. Tuning of controller gains were achieved using trial and error approach. A mathematical...
We present a city-scale crowd simulation model based on a large data set (25 million GPS data points from 28'000 volunteers recorded during a 3-day city-wide festival held in Zurich in 2013). The model is based on a spatio-temporal abstraction of the festival, focusing on event sites and event times. Thus, we assume a certain number of events (concerts, shows, etc. as it's typical at such festivals)...
To facilitate the application of foldable scissor-like element in engineering domain, this article focuses on the design of 3-loop expandable mechanism. The property of angulated element is revealed first to contribute to the modeling of theoretical model with 3-loop, and the concept of four expandable angulated elements sharing one square adaptor is then introduced to build the mechanical system...
The aim of this paper is to present the design of a linear quadratic regulator (LQR) based on optimal control of single phase grid connected inverter with an LCL output filter used in solar applications. The converter model is set in the D-Q rotating reference frame where integral action is added to the grid current in order to cancel steady state error. The controller is tested in steady state, dynamic...
As distributed systems such as automotive, medical, manufacturing automation become larger and more complex, it is difficult to test these systems. Also, the synchronization of distributed applications make the testing more difficult. In the Software-in-the-Loop (SiL) simulation, a synchronization method among clock of applications is provided for virtual hardware devices and environment. A typical...
Temporal Derivative Cellular Neural Network (TDCNN) is an important class of neural networks. These networks find a lot of application in real life mostly in the real-time image processing. However, the main challenge is to implement this network in hardware. Therefore, in this paper, sinh-domain realization of single cell architecture of TDCNN which forms the only building block of complex TDCNN...
There are many applications for which location information plays a crucial role. Finding location information by a sensor node is called the localization problem. The major challenge is to determine the location of unknown nodes based on the known location of other nodes. In this paper, a range-free localization scheme based on fuzzy-logic approach has been proposed. The localization scheme uses the...
Polycrystalline materials are solids that are made up of crystals, also called grains, that have varying sizes and orientations. Materials of this class are used in many applications, including steels, films, and electronic interconnects, to name just a few. The factors that influence how the grains in a polycrystalline form are not well understood, although materials scientists and engineers have...
This paper reports the method for the simulation of a rated machinable surface in a machined thin-walled part with a small angle of taper. The procedure for the simulation of a generating surface in the compound milling cutters set equipped with replaceable polyhedral plates within the limits of the creation of the procedure for their modeling is shown.
Usually, electrical design engineer must take care about three-phase balancing before sending the final version of the LV electric wiring. The conventional method used to verify this task was just to divide all single-phase electrical-loads between the three phases without focusing the consideration on daily load-flow variation of the electrical-loads. For this, this paper describes a necessary new...
In this work, we aim to apply an adaptive Higher order sliding mode controller for trajectory tracking mode of Multi-rotor Unmanned Aerial Vehicles (UAVs) such as a Quadrotor system. The controller consists of the addition of two terms such as nominal term based os classical sliding mode control (SMC) and an adaptive super twisting term. We start the paper by the presentation of the Quadrotor model...
This paper focus on performance analysis of Model Predictive Controller (MPC) due to the presence of constraint in its algorithm. The controllers are tested in Small-Medium Industry Steam Distillation Plant (SMISD) for regulating the steam temperature at the desired level. The performance of the controller are evaluated based on percentage overshoot, settling time and rise time. The simulation and...
This paper proposes a new decoupling control for high speed permanent magnet synchronous motor (HS-PMSM) based on the least squares support vector machine (LS-SVM) inversion system. And the online LS-SVM inverse controller is developed for the pseudo-linear system. Considering of the parameter regulating process of the LS-SVM, a proportional integral derivative (PID) controller is combined to improve...
Today's Enterprises exist in highly dynamic environment. While enterprise-architecture (EA) based models help in holistic treatment of enterprise aspects, they are static in nature and do not represent the complex dynamic behavior of enterprise as it evolves over time. Instead of relying on guideline for simulating EA models as in other approaches, we propose a comprehensive metamodel of system dynamics...
In this paper, we propose simple model following control design methods for a stable and an unstable plant. Each method is based on the pole placement using model parameters. In simulation studies, we show various cases including a nominal plant and the plant with a modeling error for a stable plant, an unstable plant, and a DC motor. These results show that the proposed methods have been superior...
Virtual Labs (VLAB) is a multi-institutional Open Educational Resources (OER) initiative, exclusively focused on lab experiments for engineering education. This project envisages building a large OER repository, containing over 1650 virtual experiments mapped to the engineering curriculum. The introduction of VLAB is a paradigm shift in an educational system that is slow to change. Treating VLAB OER...
A MapReduce cluster is usually shared by multiple users or products, aiming at accelerating their own job. In contrast, the utilization of the cluster is the main concern for the system itself. MapReduce jobs are split into independent tasks during execution. However, in practice, the number of tasks per stage for each job and the system settings are often sub-optimal to support certain workload....
A research work is performed to analyze the automatic detection performance in a surveillance area by more than three sensors to detect the unknown non-active fixed or moving target or targets. In order to solve the detection ambiguity for the multiple target case caused by the deterministic and the stochastic reason, a self-defined evaluation parameter and several variables are defined and modeled...
The internal dynamics governing the modular multilevel converter can be described by considering the total capacitor's voltages of each arm and the circulating currents. In this study, dynamics of the total capacitor voltage of the modular multilevel converter (MMC) is analyzed. Depending on the internal control approach adopted which ensure a symmetrical energy distribution in the arms of the converter,...
