The design of networked DC motor speed control platform based on WiFi

This paper describes the design and implementation of a remote brush direct-current(DC) motor speed control platform based on WiFi. The platform consists of ARM11, Moter Driver Circuit(L298N), DC, Encoder and Speed Meter, ARM11 is equipped with the Linux and selected as the main processor to realize remote control and feedback of the motor's speed in WiFi environment. And then this article uses the socket technology to realize that processor communicates with the remote client. The processor adjusts PWM to control the speed by changing the average voltage. The encoder and speed meter capture the brush DC's speed by RS485. In this paper, the details of the development of the networked control platform are introduced exhaustively, and the feasibility of the platform is verified through the experimental results.
