Conclusion For The System
- The
objective of this project is to understand the PID controller and the tuning
process for Industrial control system. Labview Software is very powerful and one of SCADA system which can monitor and controlling the process.This project are develop the understanding in science and technology
that provide a wide range scope of applications
of high performance
DC motor to drives
in area such
as rolling mills, chemical process,
electric trains, robotic
manipulators and the
home electric appliances require
speed controllers to perform tasks. DC motors have speed control
capabilities, which means that speed,
torque and even
direction of rotation
can be changed at anytime to meet
new condition.
- By
design the block diagram, we can understand about the function of it
controller, system plant, final control element, sensor and set point. The goals
of this project
are to design
and implement speed measurement for
the DC motor
using LabView. Labview is the
software that useful for engineering in industries of Malaysia. So, this assessment practices us to be
general with control system in industrial
- For the key finding, the PID
controller in LabView used to compare the desire speed and actual speed. Then,
it will send the signal to motor to make sure that it running in same speed as
a desire speed. The PID controller can
be reduced the rise time since the motor start to running and follow the desire
speed. It also eliminates the steady-state error by using integral controller
and lastly it increase the stability of the system by using derivative control.
The error is generated by disturbance that can make the speed of motor
decreased because of the friction between slotted disc and optical encoder
sensor. Finally, this project was successful constructed by using PID
controller in LabView and to proved that this project is functioning is, the
actual speed will follow the set point with having rise time, steady state
error and stability.
- system in labview is much batter when compared with the microcontroller in DC motor controller and the disadvantages of the labiew is too expensive to have DAQ card. Therefore, only big company and industry used Labview software as their monitor and controlling process in system. For example,company like Texas Instrument(the biggest semi conductor company).
- We have some factors
to be considered in our system, which is:
1) PID cycle time
2) Motor speed
3) Encoder resolution
4) PWM frequency
5) Eliminates code tuning
6) Maintains accurate PID timing
