pid loop controller with labview support

Section II gives the basics of proportional integral and derivative controller. In this paper, Section I includes the introduction to control system, dc motor and different controlling techniques of motor. the Arduino board interfaced with PID Controller in LabVIEW. The aim is to control the speed of the dc motor using the Low Cost data acquisition board i.e. The user interface was developed in an Arduino environment. It primarily functions as a device that digitizes incoming analog signals so that the LabVIEW can interpret them. A controlled DC-motor is developed allowing Arduino hardware which acts as the interface between the computer (LabVIEW) and the outside world. A control system is an interconnection of components forming a system configuration that will provide a desired system response. Here in this paper terminal voltage control method is employed. The speed of the motor can be controlled by three methods namely terminal voltage control, armature rheostat control method and flux control method.

If its speed is not same, PID Controller will try to minimize the error and bring the motor to the set point value. PID Controller compares the actual speed of the DC motor with the set speed. From tachometer, the output is sent back to the PID Controller in LabVIEW via Arduino board. Tachometer is a sensor which measures the revolutions. The speed of the dc motor will be sensed by using the tachometer. DC motor will move with the speed set by the user in LabVIEW. LabVIEW will in turn pass this speed to the DC motor using a PWM pins on the Arduino Uno board. The speed of the DC motor will be set by creating a Graphic User Interface (GUI) for PID Controller in LabVIEW. Arduino Uno board plays the role of low cost data acquisition board. DC Motor will be interfaced with LabVIEW using an Arduino Uno board. The aim of this paper is to show how DC motor can be controlled by using a PID controller in LabVIEW.

Controlling the speed of a DC motors is very important as any small change can lead to instability of the closed loop system. One of the applications used here is to control the speed of the DC motor. It can be used for various Industrial applications. The proportional integral derivative (PID) controller is the most common form of feedback used in the control systems.
