Intelligence Method for PID Controller Design in AVR System
Designing of a PID controller is a very common method for industrial process control and due to its very simple and efficient function; it is used in a wide variety of industrial applications. PID controller to reduce the steady state error and dynamic response of the system is used. PID controller design is an inevitable problem in setting the coefficients need to try a lot of trial and error,...
متن کاملThinking like Archimedes with a 3D printer
We illustrate Archimedes’ method using models produced with 3D printers. This approach allowed us to create physical proofs of results known to Archimedes and to illustrate ideas of a mathematician who is known both for his mechanical inventions as well as his breakthroughs in geometry and calculus. We use technology from the 21st century to trace intellectual achievements from the 3rd century ...
متن کاملMinimally invasive aortic valve replacement (AVR) compared to standard AVR.
OBJECTIVES Minimally invasive cardiac surgery has been developed to offer patients the benefits of open heart operations with decreased pain and limited skin incision. A limited superior median sternotomy has been shown to provide a good exposure for aortic valve replacement (AVR) and good results. In this study we report the results of minimally invasive AVR compared to standard sternotomy AVR...
متن کاملOptimal PID Controller Design for AVR System
In this paper, a real-valued genetic algorithm (RGA) and a particle swarm optimization (PSO) algorithm with a new fitness function method are proposed to design a PID controller for the Automatic Voltage Regulator (AVR) system. The proposed fitness function can let the RGA and PSO algorithm search a high-quality solution effectively and improve the transient response of the controlled system. T...
متن کاملAVR Microcontroller Implementation for Customized Sound Generation
Received Nov 1, 2011 Revised Jan 18, 2012 Accepted Jan 28, 2012 In this paper, we have proposed a technique by which customized sound can be generated using 8 bit AVR microcontroller. Any sound file chosen from computer can be integrated in microcontroller programming which is written in C and compiled by AVR libc compiler. An 8 bit DAC connected to PORT A of AVR microcontroller takes data of s...
