Hello! Did you complete the full installation path described in the install-ubuntu.sh file. It is very important to
See "Dependencies" section of the readme.md file as well. I've comleted the project quite while ago, so, some libraries may be updated and not compatible with the project.

Hey thanks for the help, it generated an executable pid file after running ./pid command and says Listening to port 4567
HELLO
How do I link that to the udacity simulator?

from model-predictive-control.

As far as I can remember the project, you just have to start your script and the simulator in correct order. Of course, if you run them locally.

Okay! I hope I am not bothering you and actually I downloaded two files for the simulator one is term2_sim_linux and the other is beta_simulator_linux. ./pid(CLIENT) is listening to the first simulator.

MY OBJECTIVE is somehow attack the car when it is going at 20mph to suddenly increase or decrease by 10mph. Do you think this is possible by manipulating your PID.cpp or main.cpp codes and how can I show that in the simulator? THANKS IN ADVANCE!!

Hi! Now I got to simulate your code, when I run in autonomous mode using "term2_sim_linux" simulator(server), it doesn't run properly for longer time , i mean the car is crashing towards one side.
DO I need to change the PID parameters of your code?

from model-predictive-control.

Well, I is quite possible. I observed that quality and performance of the controller depends on your computer. I faced the same issue when I tried to run my code on a laptop, after it was fine-tuned for the best performance on a PC. So, you may need to optimize the parameters on your own to meet your computer capabilities.

Thanks by the way!

from model-predictive-control.

Great, parameters tuning with patience is all what you need. Good luck with it!
Well, after the nanodegree I started working as a computer vision scientist. My main focus is real time video processing with artificial neural network. So, the program was quite helpful for career start.
