cruise control of cars

Cruise control can simply be a PID controller. You can use DSP builder to design your PID controller and then generate VHDL code from that. Or you can code it by hand.

first think thanks to reply

excuse me sir how can show my process

Altera_Forum · ‎03-29-2016

first look into pid controllers. Then create a simple PID model in some tool like Simulink / Matlab. Then you can work from there. Creating the PID model and simulation would be your first step.

please help me

Altera_Forum · ‎03-29-2016

but i have only program Quartus II i know is Difficult i'm really tired to Search about the code in google

i do no how i use Matlab or

please help me

I appreciate your efforts

Look at this paper: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.471.1660&rep=rep1&type=pdf

This is a good flow about implementing PIDs in FPGAs.

sir the website not work

We are sorry !

The URL does not match any resource in our repository.

it is no useful sorry sir

i have project write code vhdl about cruise control plase help me

I appreciate your efforts

Altera_Forum · ‎03-30-2016

Instead of just asking for help when you don't appear to have done any work yourself, you'll get a better response it you try doing some work yourself and come back here with specific questions about your code.

Altera_Forum · ‎03-30-2016

OK i will try thanks for you advice

ok if found program cruise control is write java there any program to compiler to VHDL

Java andvhdl are very different languages. Java is a programming language and vhdl is a hardware description language. Conversion is a manual prices you will have to do yourself.

i try to isolation cruise control by method Components

You have an input called cruise_on, you can't also have a signal called cruise_on.

You haven't included the my_components package. But if you have all the components declared in the code, why do you need a components package?

Altera_Forum · ‎04-02-2016

I deleted ( USE work.my_components.all;) but have problem what i should to do
