  • Discrete-time explicit model reference adaptive control for robotic manipulators

    Creator:
    Yuh, Junku
    Abstract:
    In this dissertation a direct approach to discrete-time model reference adaptive control (MRAC) based on hyperstability theory is proposed to control industrial robotic manipulators. For industrial robots and manipulators, which usually have highly nonlinear and complex dynamic equations and often have unknown inertia characteristics, it is very difficult to achieve...
