A new design of a submicropositioner utilizing electromagnetic actuators and flexure mechanism

In this paper, a novel XY -dimensional submicropositioner, including mechanism, control, and analysis, is successfully presented. The design of the submicropositioner utilizes a monolithic parallel flexure mechanism with built-in electromagnetic actuators and optical sensors to achieve the object of 3-DOF precise motion. From the provided experimental results, there are several main goals that have been achieved in this paper: 1) to integrate the electromagnetic actuator and the parallel flexure mechanism for planar positioning system; 2) to establish the mathematical modeling; 3) to develop an advanced adaptive slidingmode controller; and 4) to perform extensive experiments to test the realistic performance.
