Integrated structure and controller design of machine tools

The machine design process usually covers two different engineering domains: structure design and system control. The relationship between these two domains is very closed. In order to reduce the disturbance caused by parameters in either one, the domain knowledge from those two different fields needs to be integrated. So the technique of multi-object optimization will be applied to achieve multiple design objectives. To investigate the method for integrated optimization, we will use the machine tools, which are the most output in our country, as a design platform. First of all, application software of Pro/E and AnSys will be used to build the 3D model to analyze and design structure parameters based on their effect and sensitivity to the controller. Therefore, physical properties of the machine tool will be obtained. Matlab will also be applied to determine proper control parameters for the system. Finally, the technology of multi-object optimization design for machine tools will be fully established and the corresponding production competitivity is expected to be greatly raised.
