英文摘要：

An electric treadmill control system based on MSP430G2553 and BP neural network PID was developed. The main hardware circuits were designed in module mode. In order to improve the performance of speed regulation, the PID control algorithm based on BP neural network is adopted in the speed loop attaching to the current and speed double closed-loops. The flow chart of the system software design is given. The experiment results show that the system can meet the design requirements, and has good performance.
