Conjugated conducting polymer actuators, especially those based on polypyrrole (PPy), possess enormous potential for the creation of biomimetic devices, single-cell manipulators, numerous biomedical applications as well as robotics and prosthetics. This is due to their low actuation voltage, ability to operate at the macro-or microscale, large force-to-weight ratio, biocompatibility, low cost and their operation in aqueous and nonaqueous environments. This paper experimentally investigates the potential of intelligent control methodologies to improve the positional accuracy and response speed of trilayer PPy actuators. Two intelligent control techniques were designed and implemented -fuzzy logic PD+I control and neurofuzzy adaptive neural fuzzy inference system (ANFIS) control, which are fundamentally model-free control techniques. The performance of these controllers was compared to that of a conventional proportional integral derivative (PID) controller. It was found that the two intelligent control schemes significantly outperformed the conventional PID controller in both step and dynamic responses, with an improvement in rise time of at least 18 times and in settling time of at least two times. This study is the first to implement and compare fuzzy logic PD+I and neurofuzzy ANFIS PD+I intelligent control methodologies with a classical PID controller to the emerging field of conducting polymer PPy actuators and lays the groundwork for their use in functional devices.

“…The triple layer is immersed in an electrolyte allowing the current flow. One of the CP films acts as the anode, swelling (for preferential anionic interchange during the reaction) and pushing the device while the second CP film acts as the cathode, shrinking and trailing the device (John et al 2008;Yao et al 2008).

“…The triple layer was immersed in an electrolyte allowing the current flow. One of the conducting polymer films acts as the anode while the second film acts as the cathode (Garcia-Cordova et al, 2011;John et al, 2008;Yao et al, 2008). But using this configuration it is also possible to obtain movement outside a liquid electrolyte media using an ionic conducting membrane to separate the two films of conducting polymers.…”
