| Abstract: | Wireless servo-control has important application in fields of virtual reality, motion capture and so on. Design a wireless servo-control system of angular velocity based on Android phone. Use the micro-electro-mechanical sensor inside android phone to sense objects rotating angular velocity that as the control signal, bluetooth module HC-06 as the wireless communication medium, and STC125A60S SCM to control following rotation of the two-phase hybrid stepping motor in follow-up end with the PID algorithm of integral separation. The experimental results show that this servo-control system works stably, and the angular position following error is less than 0.5°. |
