SUMMARY

The discussion focuses on the development of an Adaptive Cruise Controller (ACC) for a car model, which involves tuning two separate PID controllers: one for speed following and another for distance following. While each PID controller functions correctly in isolation, issues arise when integrating them into a single ACC model. Participants suggest that the problem may stem from the coupling of the two systems, indicating a need for proper integration techniques and tuning strategies to ensure both controllers operate effectively together.

PREREQUISITES
  • Understanding of PID controller tuning techniques
  • Familiarity with adaptive cruise control systems
  • Knowledge of control system integration methods
  • Experience with block diagram modeling
NEXT STEPS
  • Research advanced PID tuning methods for multi-controller systems
  • Explore control system integration techniques for adaptive systems
  • Learn about block diagram representation and analysis of control systems
  • Investigate simulation tools for testing integrated control models
USEFUL FOR

Automotive engineers, control system designers, and anyone involved in developing or optimizing adaptive cruise control systems.

My target is to make a Adaptive cruise controller(ACC) for a car model. So i divided the task into two parts, first--- I made a speed following model, tuned a PID controller for it.
Second---- I made a distance following model, tuned a PID for this.
Now i integrated the two models into a single model so that i could switch between Distance follower or speed follower based on distance between the car under consideration and the car ahead of it. My problem is individually the two controller models work fine, but when i combined these two models to get a total ACC model, its no more working, can someone please guide me as to what might be wrong, or how to tune PID's in this model.?

Thanks in advance.

can you show us block diagrams of the 2 systems independently and how you combined them?

It sounds like you might have coupled the 2 systems in some way
