摘　　要：以C8051F020单片机为核心处理器,设计了仿人手臂形假肢的控制系统。系统采用单片机自身集成的PCA模块产生占空比可调的PWM信号用于驱动三个直流电机,采用定时器产生频率信号用于驱动三个步进电机,采用CPLD对各个关节控制量的检测并实时地反馈给控制器实现实时控制。在此基础上设计出了按键控制和语音控制两种控制方式。该系统不但结构简单、操作方便,而且可靠性高。Take C8051F020 as the core processor to design humanoid artificial limb＇s control system. The system uses the PCA module of C8051f020 to produce the PWM signal of duty-cycle adjustable to drive the three DC motors, the timer to produce the frequency signal to drive the three stepper motors, the CPLD to check each joint control quantity and feedback to the controller so that the controller can control the artificial limb instantly. There are two control modes： pressed key control and voice control. The system has some good properties such as simple structure, high reliability and easy operation.
