Wind farm power optimization via yaw angle control: A wind tunnel study

Yaw angle control is known nowadays as a promising and effective technique to mitigate wake effects in wind farms. In this paper, we perform wind tunnel experiments to study the performance of a model wind farm with five turbine rows under a wide variety o ...

Feedback MPC for Torque-Controlled Legged Robots

Marco Hutter

The computational power of mobile robots is currently insufficient to achieve torque level whole-body Model Predictive Control (MPC) at the update rates required for complex dynamic systems such as legged robots. This problem is commonly circumvented by us ...

An integrator-differentiator TIA using a multi-element pseudo-resistor in its DC servo loop for enhanced noise performance

Georg Fantner, Jens Anders

In this paper, we present an integrator-differentiator transimpedance amplifier (TIA) featuring a multielement pseudo-resistor (MEPR) in the DC feedback path for improved noise performance in the presence of non-zero DC input currents. The presented protot ...

Practical control methods for vacuum driven soft actuator modules

Jamie Paik, Matthew Aaron Robertson

Vacuum-powered Soft Pneumatic Actuator (VSPA) Modules have been described to afford advantages for rapid development of reconfigurable, multi-DoF soft pneumatic robots powered by vacuum by reducing their logistical complexity, however they also present new ...

A Miniature Multimodal Actuator for Effective Tactile Feedback: Design and Characterization

Huaiqi Huang, Tao Li

We designed a miniature multimodal actuator by combining servomotors and vibrators. The actuator is mainly designed to non-invasively deliver tactile information to human skin by high-frequency vibration and low-frequency pressures simultaneously. By utili ...

Autonomous Learning of Internal Dynamic Models for Reaching Tasks

Auke Ijspeert, Tadej Petric

The paper addresses the problem of learning internal task-specific dynamic models for a reaching task. Using task-specific dynamic models is crucial for achieving both high tracking accuracy and compliant behaviour, which improves safety concerns while wor ...

From cineradiography to biorobots: an approach for designing robots to emulate and study animal locomotion

Auke Ijspeert, Kamilo Andres Melo Becerra, Tomislav Horvat, Robin Thandiackal, Konstantinos Karakasiliotis, Navid Khajeh Mahabadi, Stanislav Yuri Tsitkov

Robots are increasingly used as scientific tools to investigate animal locomotion. However, designing a robot that properly emulates the kinematic and dynamic properties of an animal is difficult because of the complexity of musculoskeletal systems and the ...

Comparative Study of Haptic Interfaces for Bilateral Teleoperation of VTOL Aerial Robots

Felix Stephan Schill

Force feedback is a powerful sensory cue that can provide a user, remotely teleoperating a vertical takeoff and landing (VTOL) aerial robotic vehicle, with an enhanced perception of the robot motion and interaction with the local environment. The accepted ...

A wind-tunnel investigation of wind-turbine wakes in different yawed and loading conditions

Fernando Porté Agel, Majid Bastankhah

Wind-turbine wakes have negative effects on wind-farm performance. They are associated with: (a) the velocity deficit, which reduces the generated power of downwind turbines; and (b) the turbulence level, which increases the fatigue loads on downwind turbi ...
