Mutation analysis models for visual servoing in nanomanipulations

Jianguo Zhao, Bo Song, Ning Xi, King Wai, Chiu Lai
2011 IEEE Conference on Decision and Control and European Control Conference  
This paper has two purposes: investigating a featureless visual servoing approach based on mutation analysis and proposing a visual servo control method for nanomanipulations.  ...  For the first purpose, the featureless visual servoing method is needed because traditional visual servoing relies heavily on robust feature extraction and tracking, which are very difficult in natural  ...  First of all, essential concepts in mutation analysis will be presented in section II. After that, the mutation equation model for visual servoing and the controller design are given in section III.  ...

Compressive feedback based non-vector space control

Jianguo Zhao, Bo Song, Ning Xi, King Wai Chiu Lai, Hongzhi Chen, Chengeng Qu
2012 2012 American Control Conference (ACC)  
The visual servoing formulation of the controller is further applied to the motion control in nanomanipulations. Simulation results suggest good performance of the controller.  ...  In this way, image processing for feature extraction is not required, which is an essential process in conventional servo methods.  ...  Finally, the controller is applied to visual servoing for AFM based nanomanipulations, and simulation results are presented to verify the controller in section IV. II.  ...
