| Abstract |
This paper presents an overview of fault modes and diagnostics techniques in electrified hydraulic actuators. Electrified hydraulic actuators tend to be complex systems as they consist of several components including hydraulics, electric motors, and power electronic drives. Many actuator systems work in harsh environments which makes sensing, control, and diagnostics challenging. If any of the components of the electrified hydraulic system fails, then the entire system can either lose or shuts down. This is critical and costly for many applications such as industrial, mobile, and aerospace hydraulic systems. This paper aims to provide a broad review of the faults and diagnostics of the electrified hydraulic actuator systems. |
