The main objective of this paper is to improve the tracking accuracy of a linear motor's stage. A DC brushless linear motor is used to actuate a gantry stage to perform printing process. To compensate the tracking error of the gantry stage due to nonlinear friction, the dynamics of the nonlinear static friction is formulated by the Hsieh-Pan model. Besides, genetic algorithm (GA) is studied to identify...
The main objective of this paper is to establish a precision contouring control of a biaxial piezoelectric-actuated stage. The positioning accuracy of the piezoelectric-actuated stage is limited due to the hysteretic nonlinearity of the piezoelectric actuators (PEA). To compensate this hysteresis problem, a feedforward controller based on an evolution algorithm is proposed. The dynamics of the hysteresis...
