Open-loop controlThe hysteresis in piezoelectric actuator is the main factor that affects its displacement accuracy, the hysteresis model is set up by using the theory of preisach, and the research on open-loop control of piezoelectric actuator is carried out based on inverse preisach model. The ...
Closed-loop (CL) and open-loop (OL) types of motor control during human forward upper trunk bending are investigated. A two-joint (hip and ankle) biomechanical model of the human body is used. The analysis is performed in terms of the movements along eigenvectors of the motion equation ("...
one form of active open-loop control. Slow modulations display rich and complex behavior where elastic turbulence is still present, while it vanishes for fast modulations
quantum control theoryProperties of unitary time evolution of quantum systems can be applied to define quantum cryptographic protocols. Dynamics of a qubit can be exploited as a data encryption/decryption procedure by means of timed measurements, implementation of an open-loop control scheme over a ...
TAH Coelho,Y Liang,VFA Alves - 《Mechanism & Machine Theory》 被引量: 57发表: 2004年 Open-loop and optimal control of cylinder wake via electromagnetic fields The experimental and numerical investigations on electromagnetic control of cylinder wake have been performed in this paper. Experiments were...
“simple” open-loop control system can mean a steeper learning curve. It’s not easy to learn to drive a manual transmission. But if you don’t know how to drive one, you’re missing out on some nice advantages, like the ability to push start the thing if you have to, and the ...
analyzed its mathematical theory,and elucidated the theoretical basis of dual open-loop autoleveling control system.By comparing the open-loop control system,closed-loop control system and mixed-loop control system,the paper drew a conclusion that the new control system could shorten the blind area,...
The required coupling can be generated using a simple open-loop control protocol, obtained with optimal control theory. We simulate the complete preparation process, including environmental noise. Our results indicate the power of open-loop control for state engineering and measurement in quantum ...
