Multivariable Negative-Imaginary Controller Design for Damping and Cross Coupling Reduction of Nanopositioners: A Reference Model Matching Approach PROJECT TITLE :Multivariable Negative-Imaginary Controller Design for Damping and Cross Coupling Reduction of Nanopositioners: A Reference Model Matching ApproachABSTRACT:This paper presents the look and experimental implementation of a novel multi-input multi-output (MIMO) control structure using 2 negative-imaginary damping controllers to damp the first resonant mode and attenuate cross coupling effects between the axes of a piezoelectric tube scanner. The dynamics of the scanner in the lateral and longitudinal axes are identified from measured information and the look of the controller employing a MIMO framework is finished based on a reference model matching approach. The controller proposed in the paper is able to achieve a bandwidth close to to the first resonance frequency of the scanner and the proposed controller is strong against changes in resonance frequencies that are due to load changes on the scanner. Experimental results are presented to show the effectiveness of the proposed controller. Did you like this research project? To get this research project Guidelines, Training and Code...
