Pid parameters is a cluster containing the updated pid gains. This lab gives basic insight into parameters that define the motor so the student can later accurately control speed and position. Sedc motor will be interfaced with labview using an arduino board. This lab introduces students to using transfer functions to create models for how a dc motor behaves. In the tutorial dc motor speed control in labview, i will explain you a complete step by step procedure to control the clockwise and counter clockwise direction of the dc motor as well as accelerating and deacelerating it with the help of the buttons on the gui created in ni labview using serial communication between arduino and ni labview. The aim of this project is to show how separately excited dc sedc motor can be controlled by using a pid controller in labview. You can also visit the web page with resources for designing and tuning pid controllers. In addition, they run openloop feedback control with a virtual instrument to validate the dc motor model. Arduino uno, dc motor, labview, pid controller, pwm pulses, lifa.

Pid controller is used to control a simple dc motor modeled in simulink.

I am trying to use arduino to control a servo motor in labview. Labview program to control the speed and direction of dc motor. Dc motor plays a crucial role in research, industry and laboratory experiments because of their simplicity and low cost.

The speed of the motor can be controlled by three methods namely terminal voltage control, armature rheostat control method and flux control method. In this example well learn how to turn a motor on and off, and then use pwm to control the motor speed. Control pid digital usando arduino y labview parte 1. This value is equal to the feedback value of the feedback control loop.

In this section we will write labview program to control the speed and direction of dc motor. Real time dc motor speed control using pid controller in. I searched for sample codes available online using lifa and linx. Dc motor using a pid controller in labview with arduino ijsrdvol. This example shows two dc motor control techniques for reducing the sensitivity of w to load variations changes in the torque opposed by the motor load. To see how to tune the pid controller, please see the video demo andor read the blog post.
