I would like to control the gas pedal, brake pedal, steering and transmission through PID controllers, I have a Simulink model that is somewhat similar to the examples from Matlab ( Three-Axle Tractor Towing a Three-Axle Trailer) but I would like to delete the Bolck Driver Commands and Replace with PID controller. can someone help me, how can i do that.

Hi @Waseem Shatto
I guess you can select the "Driver-input-to-the-vehicle" Block, by moving your mouse cursor over the block and clicking on it. Then hit the [DELETE] key on your keyboard.
Next, find the "PID controller" block in the Simulink Library, insert the block by dragging it over to the void where you just deleted the previous block. Connect the signal arrows manually if the program doesn't do it automatically.

ok thanks, i know what i really need is: correct control for this controller, i.e. which inputs have an influence on the acceleration and which on the deceleration, steering and also the gearbox. Is there maybe an example where you can use pid controllers to control this thing instead of linear predictive driver, because in my model the steering doesn't work well with linear predictive driver.

No worries. I'm not familiar with the Three-Axle Tractor Towing a Three-Axle Trailer. However, if you can provide the mathematical models (either transfer function or state-space) for the acceleration, deceleration, steering and gear transmission, then I think it is possible to try using the PID Controller blocks.

Thanks again,
that's the problem, I was able to do it, that's why I'm asking here, maybe someone has had experience with it, or someone already has PID controllers for the controls (accelerator pedal, brake pedal, steering and gear).

Please reply in the Comment section, below my Answer or your Question.
You don't have to worry about the PID thing now. Focus on deriving the mathematical models because they are required for the PID tuning.

ok, thanks, maybe please send me an example. So a Simulink model for this purpose, then I try to adapt it to my requirements
