摘要
根据标校系统两轴电视跟踪转台的性能指标要求,采用光电编码器构成转轴的角位置反馈及角速度反馈;脉宽调制功放和直流力矩电机构成系统的执行机构;采用电流环、速率环、位置环三闭环的控制策略,基于TMS320VC6713 DSP芯片设计了全数字模糊PID控制算法,实现了电视跟踪转台伺服系统的低速和高精度定位。
According to the performance requirements of calibration system 2-axis TV tracking turntable,the system uses an optical encoder to make up the feedback of the rotor＇s angular position and angular velocity.The pulse-width modulation amplifier and the DC torque motor constitute executive body of the system.Full digital fuzzy PID control algorithm is designed basing on the TMS320VC6713 DSP.The digital closed-loop control strategy,including current-loop,velocity-loop and position-loop,gets lowspeed and high precision of the positioning of TV tracking turntable servo system realized.
