Abstract

To achieve energy saving of electro-hydraulic servo systems (EHSS), a separate meter-in and separate meter-out (SMISMO) control system is designed using two servo valves. An adaptive robust command filtered control (ARCFC) method is proposed for SMISMO system, which combines adaptive robust control (ARC) with command filtered control (CFC). ARC is used to deal with parameter uncertainty and unknown disturbances, and CFC is introduced to deal with’explosion of terms’ problem while compensating the filter errors in backstepping design process to reduce calculation. Comparative experiments show that the SMISMO system with ARCFC controller can realize the same high-precision control as the conventional electro-hydraulic system (CES), or even better, while achieving about 2/3 energy-saving.
