This study presents MATLAB/Simulink model of Sample and Hold Circuit system for the automation of transmission utility to suppress the outage of grids. The traditional fault diagnosis methods like SCADA systems, digital fault recorders, travelling wave fault locators, multi agent system and other monitoring devices are haggard upon to inform the engineers of incidents, problems and fault. In th...

An automated modelling and control design environment for serial manipulators has been implemented in Matlab/Simulink. This development was motivated by the need for a fast and insightful modelling tool, given that currently available modelling environments are not well suited for control design. The manipulator configuration is defined within a graphical user interface and the corresponding ma...

Three phase induction motor is one of the most widely used motors as industrial, commercial and residential load. This motor has the simplest construction, reliable in operation, low initial cost, easy operation, simple maintenance, high efficiency and simple speed control. The popularity of this motor has resulted into lot of research including the transient behaviour of the motor. In this pap...

We have created open-source Simulink block libraries for ITK and VTK that allow pipelines for these toolkits to be built in a visual, drag-and-drop style within MATLAB. Each block contains an instance of an ITK or VTK class. Any block connections and parameters that the user makes within MATLAB’s Simulink visual environment are converted into connections and parameters for the ITK and VTK pipel...

In this paper, a new method is introduced to implement chaotic generators based on the Henon map and Lorenz chaotic generators given by the state equations using the Field Programmable Gate Array (FPGA). The aim of this method is to increase the frequency of the chaotic generators. The new method is based on the MATLAB Software, Xilinx System Generator, Xilinx Alliance tools and Synplicity Synp...

Variable frequency transformer (VFT), introduced recently is a flexible asynchronous ac link which is used in power transferal process between asynchronous power system grids. VFT was first installed at Langlois substation, which interconnects the Hydro-Québec (Canada) and New York (USA) systems. The torque of the rotary transformer is externally altered in order to control the direction and ma...

In this paper two methods for real-time debugging and testing of a control system are proposed. The basic instruments used are personal computers, a Visual C++ compiler and MATLAB including the GUI Design Environment, Simulink, real-time workshop, xPC target, and some relevant hardware. For the first method, MATLAB functions are used to build a control system debugging and testing environment. ...

The use of networked control systems is very modern in industrial control. The evolution of computer networks, the increase of transfer speed and noise resistance caused the installation of Ethernet technologies in industry more frequent [1]. The most frequently used standard for interconnecting Matlab with industrial devices is the OPC standard. Our goal was to design a Matlab toolbox for comm...

Custom tools for MATLAB supporting analysis and design of nonlinear control systems are introduced in this paper. The paper demonstrates their use to solve sample nonlinear control problems and presents some of the MATLAB algorithms involved. A lot of attention is dedicated to a rather unusual collaboration of Simulink and Symbolic Math Toolbox that was employed in creation of the tools.
