QFT Control of a Two-Link Rigid-Flexible Manipulator

This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...

Robust Tracking Control of a Single-link Flexible Manipulator

Quantitative Feedback Theory (QFT) is employed to achieve time domain specifications on the tip position of a hybrid actuated single-link flexible manipulator. The manipulator payload conditions are varied to assess the robustness of the synthesised control system to parametric uncertainty. A combination of QFT multi input multi output (MIMO) design methods 1 (nonsequential) and 2 (sequential) ...

End-Effector Trajectory Tracking Control of a Parallel Flexible Manipulator

End-effector trajectory tracking of flexible multibody systems is often a challenging task. This is due to the fact that flexible multibody systems possess less control inputs than degrees of freedom, i.e. they are underactuated. Thus, classical approaches known from fully actuated systems cannot be applied. The complexity might be further increased, if the multibody system includes additional ...

Nonlinear Robust Tracking Control of an Underwater Vehicle-Manipulator System

This paper develops an improved robust multi-surface sliding mode controller for a complicated five degrees of freedom Underwater Vehicle-Manipulator System with floating base. The proposed method combines the robust controller with some corrective terms to decrease the tracking error in transient and steady state. This approach improves the performance of the nonlinear dynamic control scheme a...
