Abstract: The
main idea of adaptive control design theory based on the error
polynomial algebra is to make the adaptive
control
error incline to zero as time passed. It can make the adaptive control
system be steady on the basis of the theory of LIAPUNOV A M. An adaptive
control method adapted to the asymmetric cylinder hydraulic servo system
controlled by symmetric valve is presented to make the output of the
system follow the output of the reference model progressively, so that
the problems of dynamic performance asymmetry, low accuracy, low
stability, narrow bandwidth and big delay are resolved.
Key words: Servo
valve asymmetric cylinder Adaptive control Model reference Error
