Simulink Modelling and Controller Design for an Auto Cruise

This paper presents the output characteristics of different control approaches that are developed in a cruise control system. It is broadly used because it is quite simple to understand and yet the control technique evolves classical and new design methods. The mathematical modeling for linear and nonlinear dynamics model of the auto cruise is developed in this paper. For linear model design, it requires proportional plus integral plus derivative controller, artificial intelligence controller and state space input and output equations. For nonlinear model with disturbance effect design, feed forward PID controller is developed in order to nullify the wind disturbance and gravitational effect. Finally, a comparison of the output of linear and nonlinear controller on the basis of obtained simulation results.
