There have been many studies to develop the actuators with small size and fast response using the smart materials. To control the smart actuator, we need also smaller and lighter controller system. However conventional micro-controllers are not equipped with analog part and thus the control system becomes bulky compared with the small size of the smart devices. To overcome these weaknesses, we are developing one-chip micro-controller that can handle analog and digital signals simultaneously using mixed signal FPGA technology. In this paper we introduce the design of single chip controller using mixed signal FPGA device. To check its performance, we implemented a PI controller for power driving circuit in the FPGA fabric. Through experiment, it was demonstrated that the controller designed for the feedback control works well in realistic environments.
