Fault Estimation and Fault-Tolerant Control for the Pump-Controlled Electrohydraulic System

Fault Estimation and Fault-Tolerant Control for the Pump-Controlled Electrohydraulic System

This paper proposes a fault estimation and fault-tolerant control strategy with two observers for a pump-controlled electro-hydraulic system (PCEHS) under the presence of internal leakage faults and an external loading force. The mathematical model of the PCEHS is dedicatedly derived in the state-sp...
