Drifting Stabilization Along Circular Trajectories

Goal

Drifting control is the ability to maintain control of a drifting vehicle while executing high-speed, controlled sideslips around corners. The purpose of building a drifting controller can help prevent accidents and allow the vehicle to maintain high speeds and make precise maneuvers.

What was achieved

  • Stabilized the side-slip angle to match different desired curvatures and realize drifting motion
  • Achieved error dynamics and nonlinear model inversion to calculate desired operating points, steering angle, yaw rate, rear drive force and longitudinal velocity
  • Designed LQR controller for steering angle and proportional control for rear drive force
  • Held course angle error under 0.9 degrees and visualized the high side-slip maneuver process in Simulink
