Development of Control System for Artificial Muscle IPMC

The new actuating material IPMC with virtues of low driving voltage,large output displacement and good flexility has a tremendous application prospect in the micro-actuator field,such as bio-robot and medical instrument.In order to satisfy the actuating need of IPMC and make it portable,a control system was designed.This control system is composed by ATmega16L control module,D/A digital to analog conversion module,output current expansion module,keyboard module,power module and LCD display module.It can generate sine wave and square wave with bipolar voltage and high output current,which is needed when IPMC is actuated.Its frequency and amplitude can be adjusted.Meanwhile,it can achieve multichannel and time-sharing output.In addition,the functions of switching waveform,modulating frequency and voltage were tested by an oscillograph,and verified that the design was feasible.
