摘要

A new control scheme is introduced for a pneumatic servo system which contain unknown parameters, possible nonlinear uncertainties and additive bounded disturbance. The proposed control scheme is essential to achieve robust stability and good performance for the pneumatic servo system. The design of controller requires only measured input and output signals of system. Compared with other robust control schemes, this scheme not only guarantees a robust stability, but also provides a control signal which is continuous and globally, uniformly bounded. Although the output tracking error cannot be guaranteed to converge to zero, it is able to converge globally and exponentially to a residue set whose radius is an arbitrary positive constantε.
