This paper proposes a suitable digital platform based on the Xilinx Zynq®-7000 family to process the functions performed by a smart-solid-state-transformer (3ST) in smart grids (SG) application. These functions include: link to information and communication technologies (ICT), voltage transformation, integration of distributed renewable energy resources (DRER) and distributed energy storage devices...
This paper presents an implementation technique of a high resolution Unipolar Pulse Width Modulator (UPWM) for power inverter applications. Unipolar switched inverter has the advantage of a higher efficiency and lower harmonic distortion. The technique was tested in a 2kW inverter with a typical LC filter and it was achieved a Total Harmonic Distortion below 2%. Simulations and experimental results...
Many schemes have been proposed to control induction motors, however all these systems this kind of motors consist in complex systems. One of the most precise control schemes is the Field Oriented Control (FOC), although Scalar Control (SC) is simple compared to the construction of the FOC and others. In this work a SC and a FOC for induction motors are implemented. The goal of this study is to identify...
In this paper, an industrial robot interface is presented. This is suitable for different subjects related to robotics including robot kinematics control systems and actuators. Hardware and software stages are depicted. Besides, as a manner to teach students to select and calculate electrical components for a robot, it is presented a retrofit of a commercial six-degree of freedom robot arm from Nachi...
In this research a neural network is used to estimate the rotor resistance of an induction motor. A set of tools developed by Texas Instruments is used along with customized blocks such as an ANN block in order to put into operation a sensorless suitable adjustable speed drive for motion control applications. The results are discussed to verify the rotor resistance estimation by an ANN. Values for...
