The traditional motor control system application simulator is used to simulate the entire motor control. Although the operability is strong, there is a problem of poor control effect. In response to this problem, a design of an embedded multi-motor intelligent control system based on a single chip is proposed. The embedded single-chip dsPIC20F chip is used without the need for too many peripheral devices. Based on this, the system hardware structure is designed to obtain the difference in speed of the rotor of the inductor and convert it into corresponding signals to control the motor. AD / TCP-01 A / D data collector is selected, which can be used for ultra-remote control and transmission through the Internet within 300 meters. M57962AL is selected as the thick-mode single-in-line package driving mode to achieve good overcurrent protection. The NMRV075 stepper motor is used as a practical transmission device, which meets the requirements of single-chip microcomputers and has relatively large output torque. The embedded real-time operating system μClinux is used to design the task scheduling process, the single-chip computer program and the PC host computer, thereby completing the embedded multi-motor intelligent control. The system debugging is performed with the support of Proteus simulation software. From the debugging results, it can be known that the system control effect can reach up to 0.996, laying a foundation for improving the working efficiency of the motor.
