In this study, we propose a method for controlling a posture of 3D contents for handheld augmented reality (AR) applications. In in-situ AR applications, a 3D content creation phase is needed. In this case, users need to determine 3D position, rotation, and scale of 3D contents. However, general handheld devices have 2D input only. It is very hard to control 7 Degree of Freedom (DoF) of 3D cont...

Abstract: In this paper we describe a two-degree of freedom (T-DOF) configuration of a generalized predictive control (GPC) and an application for an NOx decomposition process of a combined cycle power plant. T-DOF GPC that is designed with feedforward signals, measurable disturbance signals and a reference signal is able to prevent an undesirable action that is caused by the feedforward contro...

The 3 degree of freedom (3-DOF) helicopter system is a typical higher-order times, instability, multi-variable, nonlinear and strong coupling control system. This paper presents the analysis of the mathematical model and the basic principle of PID control and fuzzy PID control, which are based on 3-DOF helicopter systems. In allusion to balance control of 3-DOF helicopter system, PID controller...

In this paper, we present optimal control for movement and trajectory planning of a various degrees-offreedom robots using fuzzy logic (FL) and genetic algorithms (GAs). We have evaluated and shown comparative analysis for three degree-of-freedom (3 DOF) and four degree-of-freedom (4 DOF) robotics arm to compensate the uncertainties like; Movement, friction and settling time in robotic arm move...

The subject of this paper is the optimal design of a parallel mechanism intended for three-axis machining applications. Parallel mechanisms are interesting alternative designs in this context but most of them are designed for threeor six-axis machining applications. In the last case, the position and the orientation of the tool are coupled and the shape of the workspace is complex. The aim of t...

Teleoperation has captured the interest of robotics researchers for more than two decades. Many focused on the stability problem when the system experiences time delays. Most of the time, guaranteeing stability has overshadowed the tracking performance. This work differentiates teleoperation systems into two groups as limited and unlimited-workspace teleoperation depending on their position tra...

This paper realized the 2-DOF controller structure for first order with time delay systems. The co-prime factorization is used to design observer based controller K(s), representing one degree of freedom. The problem is based on H∞ norm of mixed sensitivity and aims to achieve stability, robustness and disturbance rejection. Then, the other degree of freedom, prefilter F(s), is formulated as fi...

The problem of global output feedback tracking control of robot manipulators has been open for several years. In this short note we propose a computed torque plus (nonlinear) PD like controller to solve the output feedback tracking control problem of one degree of freedom (dof) Euler-Lagrange (EL) systems. We prove in this case global asymptotic stability. Our approach is the extension of our p...

This paper considers the problem of tracking and intercepting a potentially moving ground-based RF source with an autonomous guided munition that has a passive bearings-only sensor located on its nose. It is assumed that the munition has lost GPS signal lock and that it relies only on its noisy inertial measurement unit (IMU) for guidance and navigation. Bearings-only target motion analysis (TM...

A two-degree-of-freedom (two-DOF) equation of motion was derived in the frequency domain using a substructuring technique for efficiently calculating in-structure response spectrum (ISRS) considering equipment–structure interaction. The model primary structure condensed into mechanical impedance function and combined with equipment represented by single-degree-of-freedom oscillator domain. This...
