Why PIDControl Is Important

2012-03-01T15:16:00.000-08:00

Why PIDControl Is Important
PIDcontrol remains an important control tool for three reasons: past record of success,wide availability
and simplicity in use. These reasons reinforce one another, thereby ensuring that the more general
framework of digital control with higher order controllers has not really been able to displace PID
control. It is really only when the process situation demands a more sophisticated controller or a more
involved controller solution to control a complex process that the control engineer usesmore advanced
techniques.Even in the case where the complexity of the process demands amulti-loop ormultivariable
control solution,a network based on PIDcontrol building blocks is often used.

What The Gains Do
http://www.hitex.com/fileadmin/img/download/Basic_DC_Motor_Speed_PID_Control_With_The_Infineon_C167_Family.pdf

Integral Gain: Ensures that under steady state conditions that the motor speed (almost) exactly matches the setpoint speed. A low gain can make the controller slow to push the speed to the setpoint but excessive gain can cause hunting around the setpoint speed. In less extreme cases, it can cause overshoot whereby the speed passes through the setpoint and then approaches the required speed from the opposite direction. Unfortunately, sufficient gain to quickly achieve the setpoint speed can cause overshoot and even oscillation but the other terms can be used to damp this out.
Proportional Gain: Gives fast response to sudden load changes and can reduce instability caused by high integral gain. This gain is typically many times higher than the integral gain so that relatively small deviations in speed are corrected while the integral gain slowly moves the speed to the sepoint. Like integral gain, when set too high, proportional gain can cause a "hard" oscillation of a few Hertz in motor speed.
Derivative Gain: Can be used to give a very fast response to sudden changes in motor speed. Within simple PID controllers it can be difficult to generate a derivative term in the output that has any significant effect on motor speed. It can be deployed to reduce the rapid speed oscillation caused by high proportional gain. However, in many controllers, it is not used.

Project poster

2012-02-14T08:07:00.001-08:00

Poster Guidelines:·
Poster boards are A1 size·
Ask the technicians for one during lab sessions·
One board per group only (think before you stick anything to it!)·
You are responsible for printing, this can be several A4 sized pieces or one large A1 piece·         Remember to use high quality images and be aware of what things will look like at the final print size.·
There are no official rules for how to design your poster, make it look professional and ensure you include your project title, student names and group number somewhere.·
Consider generating a QR code and placing this on your poster with a link to your blog·
It is your choice if you present your poster in portrait or landscape form. Try sketching the layout of your poster design before you start adding the details.
Attached is a template including a large size University crest for you to modify.

Images as Figures

There are many scenarios where you might want to accompany an image with a caption and possibly a cross-reference. This is done using the figure environment. The following code sample shows the bare minimum required to use an image as a figure.

\begin{figure}[htb]
\includegraphics{image.png}
\end{figure}

The above code extract is relatively trivial, and doesn't offer much functionality. The following code sample shows an extended use of the figure environment which is almost universally useful, offering a caption and label, centering the image and scaling it to 80% of the width of the text.

\begin{figure}[htb]
\centering
\includegraphics[width=0.8\textwidth]{image.png}
\caption{Awesome Image}
\label{fig:awesome_image}
\end{figure}

The figure environment is not exclusively used for images. More information on the figure environment and how to use it can be found in Floats, Figures and Captions.
