摘　　要：设计了一种用于IPMC电制动聚合物的驱动电路,该驱动电路能够提供IPMC低频双极性的可程控信号,输出信号的功率可以达到2W,具有很强的带电流能力。控制系统的主控芯片为AT-mega16单片机,外部电路包括D/A数模转换模块、信号发生模块和信号放大模块3大部分。设计了输出信号的控制软件,可以输出方波、三角波、正弦波和组合波形。通过将该控制系统与信号发生器驱动IPMC的输出结果进行比较,进一步验证了控制系统的可行性。A driving circuit was designed tor IPMCs which is a new kind of electro - active polymer. The driver circuit was able to provide the IPMC with low - frequency and bipolar programmable signal. The power of output signal reached 2 W with large current. The main chip of control system was a ATmegal6 microcontroller. The external circuit was composed of a D/A converter mod- ule, a signal module and a signal amplification module. The software for the control system was designed to output square wave, triangle wave, sine wave,and the combination of the waves. The IPMC motion displacement driven by the control system was compared with that driven by a standard signal generator. The result of compare showed the control system was feasibility to actuate IPMC.
