Modelling and system identification of a high precision measurement machine

International Journal of Manufacturing Research (IJMR), Vol. 3, No. 2, 2008

Abstract: This paper presents methods of parameter determination for models of a continuously scanning Universal Measuring Machine (UMM). The UMM measures parts by actuating linear and rotary motors. The parameters of these motors must be determined for high performance control and decreased tuning time. The machine tool parameters are determined both by a manual parameter determination approach using tailored tests and knowledge of the machine parameters as well as by system identification. A comparison of both methods shows that system identification can be used to accurately determine the motor parameters. Potential adaptive auto-tuning of the machine using this approach is discussed.
