Tuning PID Controller for Self-Driving Cars

A PID controller is a control loop feedback mechanism that calculates the difference between a desired setpoint and the actual output from a process, and uses the result to apply a correction to the process. PID Controller find wide range of applications in industrial and robotic process control applications. In context of Self-Driving cars, they play a important role in controlling driving parameters like steering, throttle etc. The complex algorithms used in Self-Driving cars essentially calculate a trajectory and the velocity for self-driving car to drive. Autonomy can only be realized if the car follows the trajectory with the given speed. This is exactly where PID controller plays it role to ensure the self-driving car adheres to the computed parameters. Any deviation from the computed parameters means unforeseen or catastrophic results. <a href="https://medium.com/@madhusudhan.d/tuning-pid-controller-for-self-driving-cars-3813f7f18eb0">Website</a>
