Paper Abstract

It is usual to use sensors for controlling an electrostrictive polymer (EP) actuator system. However, it may make the whole actuator system larger and more complex. Thus, it is quite difficult to use some sensors for building a simple and small EP actuator system. In this paper, a technique based on neural networks is proposed to control a simple EP actuator without any sensor. First, a closed loop controller with a sensor is applied to control this EP actuator and its data are measured. Then these data and the characteristics of EP polymers are used to train a neural network offline. The resultant neural network is applied to control a simple EP actuator with no sensor. The experimental data under the proposed technique are compared with those under the closed loop controller and its result is discussed.
