Optimal control system for safety angle of human ankle joint during sports training.

In order to solve the problems of traditional ankle joint safety angle control systems, such as poor stability of the PWM control unit and low accuracy of ankle joint angle control, this paper designs the human ankle joint's safety angle optimization control system. Firstly, the human ankle joint safety angle is determined by judging the changes in the physiological characteristics of the ankle joint during sports training. Secondly, the hardware part design of the new optimized control system is completed by designing a power supply module, sensor module, and serial communication module. Thirdly, the software part of the new optimized control system is designed through the main program design, performance functions design, and PWM control unit reinforcement design. Finally, by simulating the system operation environment, the design comparison experiment results show that the stability of the PWM control unit and the accuracy of ankle joint angle control are greatly improved after the optimized system compared with the traditional system.
