Abstract

An adaptive controller with state constraints is proposed for hydraulic systems

where a finite time disturbance observer and an adaptive controller are designed following barrier Lyapunov function. The finite time disturbance observer ensures disturbance estimation accuracy

and the adaptive controller handles parametric uncertainties. Barrier Lyapunov function is employed for state constraints to stabilize the closed loop system. Theoretically

the controller guarantees asymptotic tracking performance. Experimental results show that the algorithm can constrain the output velocity and acceleration

the maximum static tracking error is 0.06 mm when the amplitude of the desired tracking trajectory is 10 mm

and the maximum relative tracking error reaches 0.6%

thus the system tracking accuracy is obviously improved.
