Yaw Rate and Sideslip Control using PID Controller for Double Lane Changing

Vehicle behavior and stability can be observed through the computer simulation using mathematical modeling approach consist the configuration of vehicle multibody system. This paper presents the estimation and control of the yaw rate and sideslip through vehicle lateral dynamic model with a PID controller. The stability analysis is conducted to a single-input-two-outputs (SITO) plant of front-steering-only vehicle model to observe the system response during double lane changing maneuver with constant speeds of 40 km/h and 90 km/h. Results show that a single-input-single-output (SISO) PID controller able to enhance the cornering limit by reducing the sideslip and optimized the yaw rate, especially for slow speed vehicle in order to maintain its stability states.
