Attitude Control of Rhoenrad by Internal Mass Motion

Attitude Control of a Rhönrad by Internal Mass Motion ∗

Rhönrad is a gymnastic equipment that is interesting in terms of dynamics and control. The control method of the Spiral motion by the mass motion in the Rhönrad was clarified. First, the condition for a steady Spiral motion with arbitrary mass position was obtained. Then, by using the linearized equation of motion, the control method to control the attitude of the Rhönrad by the mass motion in ...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Internal models for motion control

This paper is a review of different approaches and models underlying the voluntary control of human hand-arm movement. These models, dedicated to artificial movement simulation with application to motor control, robotics and computer animation, are categorized along at least three axis: Direct vs. Inverse models, Dynamics vs. Kinematics models, Global vs. Local models. We focus on sensory-motor...

Rotational Motion Platform for Emulating Spacecraft Attitude Control

This research develops and evaluates a robotic rotational motion platform to test lunarlanding-like attitude, sensing and control. The platform is equipped with thrusters, sensors, and computer control and is restricted to orientation maneuvers. The platform is mass balanced and suspended on a bearing that accommodates 60 degrees of excursion in roll, pitch and yaw. The platform operates in a c...
