Identification and Quantitative Feedback Control of Precision Mechatronic Systems


Article Preview

This paper proposes a robust position controller for a precision mechatronics system, based on the quantitative feedback theory (QFT), to achieve high accuarcy and consistent tracking performance even in presence of considerable structural dynamic uncertainties and external disturbances. Tthe dynamic characteristic of precision mechatronics system is experimentally identified with close-looped identification method, taking account of system uncertainties, and then a QFT controller is designed. Simulations are carried out to validate the efficience and effectiveness of the proposed controller.
