%X A nonlinear tracking controller was designed and applied to a class of aerial pneumatic servo systems for which the connection port comprises a non-negligible restriction.The pressure in the chamber of this system is difficult to be controlled because of the servo valve and the connection port forms a double restriction.A modified feedback linearization controller was proposed to avoid this singularity caused by the double restriction.The linear matrix inequality (LMI) was then used to ensure the stability of the tracking error.Simulation results show that the proposed controller has a good disturbance rejection and dynamic properties.
