This research investigates the problem of robust control of a nonlinear, fast-dynamics, high-precision planar manipulator with a limited workspace. Starting from a mathematical model formulated in terms of Euler-Lagrange dynamics, the proposed approach considers, given the limitations of the physical system, that some...
Direct current (DC) servo motors are essential in industrial automation and robotics, where precise position and speed control are critical; however, they require high-performance control strategies. This study investigates an experimental framework for the modeling and control of a DC servo motor using system identifi...

Flexible joint robot manipulators (FJM) exhibit high nonlinear dynamics and coupling effects, which make their control a challenging task. This paper proposes a fractional order PID (FOPID) cascade control strategy for a 2DOF FJM. The controller performance is compared with that of a sliding mode controller (SMC) under...

Cable-driven manipulators have garnered increasing attention in robotics owing to their lightweight structure, flexible transmission mechanisms, and large operational workspace. However, the strong nonlinear dynamics, parameter coupling, and external disturbances inherent in cable-driven systems pose significant challe...

This paper presents a Koopman-based data-driven kinematic modelling and tracking control framework for a 7-DOF manipulator. State and squared-state lifting functions map the nonlinear forward kinematics into a linear lifted space, where system matrices are identified via ordinary least squares and stabilised by scaling...
