Energy saving is an important issue for pneumatic systems. The pneumatic system is difficult to determine its precise mathematical model, thus modeling error should be taken into account in its control. In the view point of robust control, improvement of energy efficiency has been discussed in the paper. Energy efficiency is the ratio of input energy to pneumatic actuator and to the load. This problem cannot not be treated in the H∞ control directly, and modified mixed sensitivity problem based on dynamic impedance matching is proposed. Simulation results verifies the effectiveness of the proposed method.
