摘要
针对步进电机型力促动器,设计了一种基于DSP的力促动器控制系统,并进行了测试。系统以TMS320F28069型DSP作为主控制器,采用ADS1259高精度A/D转换器采集传感器Load Cell输出力信号,通过DSP片上PWM模块输出电机控制脉冲给电机细分驱动芯片TMC389,驱动步进电机转动,形成力控制闭环。系统软件采用PID控制算法来校正力促动器输出偏差,并给出了控制程序流程图。实验测试结果表明:该控制系统具有良好的响应特性和较强的抗干扰能力,满足主动光学实验系统的要求。
A control system based on DSP is designed for stepper motor type force actuator. In this control system,TMS320F28069 DSP is employed as main controller,while high precision ADC ADS1259 is used to collect output force signal of sensor,by DSP output motor control pulse to micro-stepping driver TMC389,driving stepper motor to rotate and form force control close-loop. System software uses PID control algorithm to correct output deviation of force actuator,and control program flow chart is given. Experimental test results show that this control system has good response characteristic and strong interference anti-interference capability, and meets requirements of active optics experimental system.
