Nanometer positioning was realized in a DC-motor and ball-screw-driven stage by a high gain controller. With effecting of friction on microdynamic characteristics and steadystate errors of the stage
it is a major obstacle to the achievement of nanometer positioning. In this paper
a high gain PID control structure was designed with proportional and derivative terms placed in the feedback path. Controller parameters were calculated by multiple closed-loop poles placement according to the macrodynamics alone and no friction modeling and compensation were necessary. Experimental and simulated results indicate that the PID controller can provide a sufficiently high loop gain to suppress friction effect so that single-step nanometer positioning and uniform responses of micro-motion and macro-motion are achieved. In point-to-point positioning for step heights from 10 nm to 10 mm
the positioning error is within ±2 nm.
