PWM control of a three-phase inverter using FPGA board

Description of the open EMP1270 card EPM1270:embedded CPLD device equipped with:Operating frequency: 50MHz, Operating Voltage: 1.5 3.3V,Package: QFP144, I/O: 116, LEs: 1,270, the equivalent of 4,000 logic gates, Debugging programming: JTAG, AMS1117-3.3: 3.3 V voltage regulator. FPGA board The architecture of the PWM control of the inverter in VHDL The processes run in parallel in VHDL. The architecture of the MLI command Frequency divider: The asynchronous counter is based on the frequency divider. It is a simple D flip-flop whose inverted output is sent to its D input. Thus, at each rising edge of the clock input, the data transferred to the output is complemented Frequency divider The frequency of EPM1270 is 50 MHz, the value we need at the output is equal to the frequency of the triangular signal from PART 1, which is 2 kHz. output is equal to the frequency of the triangular signal from PART 1, which is 2 kHz. So we will divide the 50 MHz by 2 kHz to obtain the value of div clock. =...

Control robot with MATLAB (GUI)

MATLAB MATLAB is a matrix calculation software with simple syntax.With its functions specialized functions, MATLAB can also be considered as a programming language programming suitable for scientific problems. MATLAB is an interpreter: the instructions are interpreted and executed. line by line.MATLAB works in several environments such as XWindows, Windows, Macintosh There are two operating modes: 1. interactive mode: MATLAB executes the instructions as they are given by the user they are given by the user executive mode:MATLAB executes a "?chier M" (program in MATLAB language) line by line. in MATLAB language). MATLAB environment Command Window: In this Window, the user gives the instructions and MATLAB returns the results. Graphical Windows: MATLAB plots the graphs in these Window M Files: These are programs written in MATLAB language (written by the user). Toolboxes: These are collections of M files developed for specific application domains. specific application domains (...

Creation and train model to process extracting meta data from pictures of receipts, automatic categorization and make prediction using OCR AI

Architecture of The Proposed System The Flowchart Diagram shows the design for optical character recognition. It represents the steps involved in the construction of the system and the flow of data. The system is divided into four different main stages. Flowchart Diagram Major phases of our OCR These phases are as follows: Image acquisition : To capture the image from an external source like scanner or a camera etc. Preprocessing : Once the image has been acquired, different preprocessing steps can be performed to improve the quality of image. Among the different preprocessing techniques are noise removal, thresholding and extraction image base line etc. Character segmentation : In this step, the characters in the image are separated such that they can be passed to recognition engine. Among the simplest techniques are connected component analysis and projection profiles can be used. However in complex situations, where the characters are overlapping broken or some noise is present...
