Model Predictive Control of a Multi-Mode Suspension System Using Preview Information and Weight Optimization
(The American Society of Mechanical Engineers (ASME), 4/24/2023 )This study examines the effectiveness of a model predictive controller (MPC) on the multimode active suspension concept to reduce driver absorbed power. A multimode suspension uses additional degrees-of-freedom beyond a ... -
On the Benefits and Limitations of Modulated Damping With Passive Motor Control
(The American Society of Mechanical Engineers (ASME), 5/15/2023 )Conventional emulated damping, in which velocity feedback is employed in combination with motor current control to emulate damping, is used in a number of mechatronic applications. As known in the field, although such ... -
Control Oriented Modeling, Experimentation, and Stability Analysis of an Autorotating Samara
(The American Society of Mechanical Engineers (ASME), 5/15/2023 )This paper presents a control-oriented model for describing the steady-state and dynamic behavior of a single-winged samara seed-pod in autorotative descent. A negligible lateral center of mass motion and constant, prescribed ... -
Model-Free H∞ Output Feedback Control of Road Sensing in Vehicle Active Suspension Based on Reinforcement Learning
(The American Society of Mechanical Engineers (ASME), 5/2/2023 1)An active suspension system ensures the controllability of a vehicle in the vertical direction, which greatly enhances the control redundancy and safety of an intelligent driven vehicle. However, many calibrated model ... -
Rotorcraft Robotic Landing Gear With Locking Mechanisms
(The American Society of Mechanical Engineers (ASME), 4/26/2023 )Robotic landing gear (RLG) for rotorcraft improves performance in landing on sloped uneven terrain, unprepared areas, and ship decks. The interaction between the feet of the RLG and the landing surface are pivotal to a ...
