Design and Position Control of AF Lens Actuator for Mobile PhoneUsing IPMC-EMIM

摘要

IPMC-EMIM (Ionic Polyer Metal Composites + 1-ethyl-3- methyl imidazolium trifluromethane sulfonate, EMIM-Tfo) is fabricated by substituting ionic liquid for water in Nafion film, which improves water sensitiveness of IPMCand guarantees uniform performance regardless of the surrounding environment. In this paper, we will brieflyintroduce the procedure of fabrication of IPMC-EMIM and proceed to introduce the Hook-type actuator using IPMC-EMIM and application to AF Lens actuator. Parameters of Hook-type actuator are estimated from experimental data.In the simulation, The proposed AF Lens Actuator is assumed to be a linear system and based on estimated parameters,PID controller will be designed and controlled motion of AF Lens actuator will be shown through simulation.
