Active Suspension Systems

Definition

Active suspension systems are advanced vehicle suspension systems that use sensors and actuators to actively control the vehicle's ride height, damping, and overall stability. These systems adjust in real-time to varying road conditions, improving ride comfort and handling by reducing body roll, pitch, and vibrations experienced by passengers. The motivation for developing active suspension systems stems from the desire for enhanced vehicle performance and safety, leading to their integration in adaptive control frameworks.
