【Abstract】 The principle of the nanotechnology-stage is introduced and the electromagnetic force which drives the stage is calculated and analyzed.The models of the analog inner loop and the fuzzy outer loop of the stage in X-Y direction are established according to the mechanical equations.The feedback control using the inner loop and outer loop is studied,and the method of the inner loop control with the non-acceleration sensor and the fuzzy outer loop control is proposed. The simulation results show that the models have well dynamic performance and high stability.更多还原
