Vehicle Active Damping Control with Considering Time Delay
Vehicle Active Damping Control with Considering Time Delay

A model predictive control (MPC) based active damping controller for automotive driveline oscillations with time-delay consideration is proposed. A simplified driveline model considering time delay is modeled and converted to a linear parameter varying state space equation. Based on the model and model predictive control theory, an active damping controller is designed for drivability and comfortability improvement. In order to verify the designed controller, a driveline with engine is modeled to simulate the tip-in/out driving operation. An MPC active damping controller without considering time delay is simulated together with the proposed controller. The simulation results show that, by adopting the new MPC active damping controller, the vibration of the vehicle is reduced and the drivability and comfortability are improved.
