Control of conducting polymer actuators without feedback: simulated feedback control approach

Conference Paper


Abstract


  • Recently, there has been significant interest in

    conducting polymer actuators including their applications in

    micro devices and micro manipulation. A feedback control

    system is usually used to enhance the positioning ability of these

    actuators in order to widen their application areas. To this end,

    a feedback sensor is employed to acquire the position feedback

    information for implementing the control system. However, a

    feedback sensor is extremely large in size compared to the size

    of the conducting polymer actuators. With this in mind, this

    paper proposes a sensorless control scheme without the use of a

    position feedback sensor, which we call the simulated feedback

    control approach. It has a feedback loop based on the actuator

    model, not requiring a physical sensor. With an accurately

    identified system model, this control strategy has shown an

    excellent control performance when following a displacement

    input experimentally. The control performance of this control

    scheme has been compared to that of a feedforward-gain control

    scheme. The proposed control strategy can be extended to other

    smart actuators or systems, for which the use of a physical

    feedback sensor may not be practical.
