This paper proposes a Robust Subsystem-based Impedance Model Predictive Control (RSI-MPC) framework for the task-space control of flexible manipulators. Controlling flexible-link manipulators poses significant challenges due to their distributed dynamics, structural vibrations, and sensitivity to external disturbances....

A new control scheme is presented in this work for robotic manipulators with model inaccuracies and external disturbances. The strategy is designed in two stages. First, a nonlinear controller is designed on the basis of the nominal system model to satisfy prescribed trajectory-tracking constraints. This controller is...

This paper addresses the mathematical modeling and control of an aerial manipulator system comprising a quadrotor as the uncrewed aerial vehicle and a robotic arm as the manipulator. The dynamic model is established by identifying the overall center-of-mass velocity and the system's orientation as constraints, yielding...
Residual vibration of industrial manipulators can limit positioning efficiency and dynamic accuracy during high-speed motion. This study develops an integrated vibration-suppression framework for a rigid-link manipulator with flexible-joint dynamics. A controller-oriented rigid–flexible model with lumped disturbances i...

An adaptive terminal sliding-mode controller integrating a dual-feedback Improved-RNN with a barrier-function-based super-twisting mechanism is developed, which achieves the lowest nominal tracking RMSE and the shortest nominal settling times for both joints.
Experimental results on a 6-DOF robotic manipulator demonstrate that the proposed TMPC method effectively compensates for uncertainties and handles sliding mode boundary layer residual errors, achieving high-precision robust trajectory tracking while ensuring adherence to state and torque constraints.
