In this paper, we present a way that can implement the vector control Algorithm of induction motor and PWM signal generation on the basis of Matlab Simulink environment. The overall system model is designed by Simulink toolbox for vector control of induction motor, and then implement experiment with the DS1103 board of dSPACE. Although we are not coding the system, it is capable of doing simulation and experiment simultaneously. That is why Matlab and dSPACE board compiler can generate the '*.c' and '*.obj' files on the designed system automatically. After considering about hardware structure and driving system in Ds1103 board we verify the availability of Proposed method through in a comparison/analysis between simulation and experiment.

In this paper, a simulation system based on X-Plane and MATLAB/Simulink for multiple UAVs is presented. For the conceptual design of this proposed system, a hierarchical system architecture for multiple UAVs is presented. This architecture has object-oriented data structure which consists of three objects (UAV status, mission and task, and environment) and a hierarchy consisting of four layers (decision making layer, task assignment layer, path and motion planning layer, and collision avoidance layer) is also proposed. In addition, this paper shows a implementation of simulation system based on the proposed system architecture using X-Plane and MATLAB/Simulink. The result of simulation from the developed system in this paper validate capability of application for multiple UAVs in real environment.

The conventional PI controller has been widely used in industrial application due to the simple control algorithm. But it is very difficult to find the optimal PI control gain. Therefore in this paper to obtain optimal performance fuzzy proportional-plus-integral controller for the vector control system of an induction machine is presented. The simulation model is created in MATLAB/SIMULINK. The simulation results demonstrate the good performance of this system.

In this paper, enhanced stand-alone operation and development of Matlab/Simulink model of emergency diesel based hybrid energy system is presented. Simulations based on the remote community or islands were performed for PV-diesel-battery hybrid system. Modeling of PV-diesel-battery integrated system is done to perform under the solar radiation and load conditions on Matlab/Simulink platform. The models of diesel generator unit, battery energy storage system, PV and frequency-power control are developed and simulation studies have been carried out under various conditions using Matlab/Simulink and SimPowerSystem. It is demonstrated that the proposed system can provide reliable and good quality power to the customers in diesel synchronous generator-based hybrid energy systems.

This paper designed IQ imbalance estimator and compensator to cancel the IQ imbalance error in DVB-T system using OFDM by Matlab. Among Matlab model, we designed and implemented IQ imbalance estimator and compensator by System Generator of Xilinx and Matlab model compared with Xilinx System Generator Model for FPGA implementation. As a result of simulation, we confirmed that both model estimated and compensated IQ imbalance error very well. Also, we verified the performance through hardware co-simulation, timing analysis and resource estimation with Xilinx Spartan3 xc3s1000 fg676-4 target Device.

In this paper, based on MATLAB which has characteristic that is simply applied to control algorithm and source modeling, photovoltaic modeling is implemented. Photovoltaic modeling is similarly performed PV array and simulated. Also, in order to output maximum power of PV, MPPT control is simulated. Moreover, simulation of converter is performed by means of PLECS (Piece wise Linear Electrical Simulation) which is easily made schematic of power electronics. Also, we compare simulation results and Sharp PV module and Suntech PV module. Finally, informative simulation of PV generation system is provided.

This paper presents a new analytical representation and simulation of the phase inductance of a Switched Reluctance Motor(SRM) using Matlab/M-file. This simulation method has many advantages: it is free from expression, can be applied widely, demonstrates inductance profile using motor parameter only, and save run time. Moreover, this simulation method can be easily realize various SRM model unlikely the existing method that limited itself to one model. And analytical expression for inductance profile is welcome as it allows for easier analysis of the motor, for it can bring insight in it working, in formulating control strategies and in achieving high accuracy in performance computations.

This study suggests a modeling of grid-connected wind power generation system that has induction generator, and aims to perform simulations for outputs by the variation of actual wind speed and for fault current of wind generation system by the transformer winding connection. This study is implemented by matlab&simulink. The simulation shall be performed by assuming single line to ground fault generated in the system. Generator power, rotor speed, terminal voltage, system voltage, and fault current shall be observed following the performance of simulation. The fault current change will be dealt through the simulation results for fault current of wind generation system following the grid-connected transformer winding connection and the simulation result by the transformer neutral ground method.
