The realization of the developed control law is
available under the data feedback of actuator position, velocity, and pressure. With properties of robot
dynamics, the closed-loop stability with the proposed controller is proved by using Lyapunov analysis.
The trajectory tracking performance of the robot with the presented controller is evaluated through
applying sinusoidal signals and circular signals. The results shown that the adaptive robust controller can
exhibits excellent trajectory tracking performance for any inputs even without a prior knowledge. On the
other hand, the proposed adaptive robust controller has some disadvantages, optimal tuning of parameters
is difficult since many control parameters exist, and more information is required, such as velocity, load
force of the hydraulic industrial robot, which should be solved to make it available in actual high real time
control system as a good alternative
