Observer-based proportional integral derivative control for trajectory tracking of wheeled mobile robots with kinematic disturbances

作者:

Highlights:

• A novel observer-based PID controller for trajectory tracking of wheeled mobile robots is presented.

• The kinematic model of the vehicle is transformed into a set of decoupled systems, simplifying the control design stage.

• The kinematic disturbances affecting the system are compensated through the use of an observer.

• A proportional integral derivative controller achieves asymptotic stability of the closed loop system.

• A rigorous Lyapunov-based stability analysis demonstrates the validity of the novel controller.

• Numerical simulations show that the new controller outperforms a feedback controller and a finite-time controller.
