  • A straight-line motion tracking control of hydraulic

    Feb 01, 2002 · The resulting control law has been applied to straight-line motions of a 13 ton hydraulic excavator with a bucket (end-effector) speed of 0.5 m/s, a speed level at which skilful operators work. The accuracy achieved was mostly within 3 cm for surfaces with various inclinations and over broad ranges of joint motions, which is far better than that of an expert operator.

  • Control of a heavy-duty robotic excavator using time delay

    Jul 01, 2002 · In this paper, we apply time-delay control with switching action (TDCSA) using an integral sliding surface (ISS) to the control of a 21-ton robotic excavator and validate the proposed control algorithm through experiments on a straight-line motion tracking control. In addition, we show the advantage of the TDCSA using an ISS.

  • SELF-TUNING CONTROL OF AN ELECTRO-HYDRAULIC ACTUATOR SYSTEM

    ABSTRACT. Due to time-varying effects in electro-hydraulic actuator (EHA) system parameters, a self-tuning control algorithm using pole placement and recursive identification is presented. A discrete-time model is developed using system identification method to represent the EHA system and residual analysis is used for model validation.
