Controllers design of an active suspension system based on half car model

Most automobile suspension systems use passive components which are combination of spring and damper only. These components can only store and dissipate energy, and lack the capability to inject energy into the systems. The parameters of these components are generally fixed and do not vary with oper...

These components can only store and dissipate energy, and lack the capability to inject energy into the systems.

In this project, hydraulic actuators are considered in parallel with the passive components to make the systems active suspension so that the system will have the ability to store, dissipate and introduce energy to the system.
