Simulation results

  • Green: reference speed (velocity of CoG/radius of the wheels)
  • Cyan: front wheel speed (angular velocity)
  • Red: rear wheel speed (angular velocity)
  • Yellow: velocity of CoG
  • Magenta: output of the bang-bang controller of the front wheel
  • The yellow line between 0 and 1 is the slip of the front wheel
  • Blue: deceleration of the bicycle
  • Yellow: friction force of the front wheel
  • Cyan: brake torque of the front wheel
  • Magenta: friction force of the rear wheel
  • Red: brake torque of the rear wheel
