This paper concerns with the design and implementation of a microcontroller based PID controller for the purpose of controlling PMDC motor speed. The design had been done using MATLAB and Simulink and the system then simulated using Proteus, in addition to a practical physical system. The controller was implemented on an Arduino Uno board to control the speed of the motor at a desired value with the...
Electro Mechanical Miniature Circuit Breaker (MCB) has been introduced under LT Protection Scheme since 1910 for protection against short circuit faults. In the present days a good number of areas have been explored on intelligent circuit breakers like AI incorporated Vacuum Circuit Breaker, SF6, and LV DC Breaker and so on. The aforesaid breakers are single port based and for a single load. In this...
An effective approach to implement control algorithms using code auto-generation is presented. Using MATLAB and C languages as input, an optimised pure C code is generated using a custom transcompiler. The considered solution is focused on microcontrollers from the STM32 family but any other can be used due to flexibility of the presented system. Controller development for a laboratory thermal process...
The presented PROFIBUS DP Slave Shield creates a link between a PROFIBUS DP network and a microcontroller or embedded controller. The hardware can be used as an extension module for different embedded controllers with sufficiently fast IO. The system opens possibilities to connect virtual systems or Hardware-In-the-Loop systems running real-time MATLAB models to a PROFIBUS DP network running up to...
This paper presents a new approach to automatic code generation of advanced control algorithms, primarily model predictive control schemes, for microcontroller-based embedded systems. The main part of the developed tools, the transcompiler, makes it possible to effectively translate the algorithms described in a high-level language (MATLAB) into C language code for the chosen hardware platform. Implementation...
The ability of the Arduino platform to enhance student interest and performance in science, technology, engineering, and mathematics (STEM) courses, while fostering skills that are important prerequisites for future IT careers, has been proven more than once in the past years. But can the future be crafted without the past? We believe that many past inventions crave the future, so their understanding...
This paper basically provides a real time model of a low cost wheel chair based on the guiding movement of the retina, for the persons disabled with quadriplegia. This model is expected to benefit the poor paralyzed people as it provides a simplified low cost model of the wheel chair. The model is realized through matlab in serial communication with the special purpose microcontroller IC manufactured...
This paper describes an updated version of the hardware used for an undergraduate control systems laboratory, and describes a complete set of laboratory experiments for an introductory control systems course using the hardware. It applies to a system described in a previous paper [1]. We continue to update the hardware and the software for this system because it is has proven to be a very successful...
The project presents an idea to provide visually impaired people access to any printed material or soft copies available on the computer. The project is a suitable alternative to Braille books. This initiative enables a blind person to read texts which are not available in the Braille format. An image sensor enables the user to take images of the text to be read. The dots of the script sensed by the...
The project aims at developing a prototype boat that is capable of autonomously sailing and navigating its way through obstacles present around it. Apart from moving on a pre defined path the boat can intelligently avoid obstacles in the path through its ability of decision making using fuzzy logic. Calculations of fuzzy logic as well as deciding inputs for the path direction to be sent to the micro...
This paper proposes the hardware design and implementation of a Microcontroller based single-phase simplified seven-level inverter for PV system. Multilevel inverters tender high power capability, associated with lower output harmonics and lower turn-off losses. This work informs a multilevel inverter for PV system using an H-bridge output stage with bidirectional auxiliary switches. The inverter...
