【摘要】 摘要:为提高输入信号未知条件下伺服系统跟踪性能,提出多次跟踪控制方法。研究多次跟踪控制方法的结构、理想情况下系统特点、多次跟踪系统的实现方案以及理想情况下多次跟踪部分的作用。应用于光电跟踪伺服系统,大幅提高系统型别及跟踪精度。实验结果表明:采用3次跟踪控制方法,系统达到V型,跟踪匀加加速度无静差;在跟踪探测器输出延迟0.04 s情况下,对最大速度为50(°)/s、最大加速度为30(°)/s~2的等效正弦信号稳态跟踪精度小于1’,比PI控制下系统的跟踪精度提高30倍。更多还原

【Abstract】 A multiple tracking control method was generated to improve the tracking performance of a servo system.The multiple tracking control structure,system characteristic on ideal condition and the effect of multiple tracking parts were researched.The results show that when it is applied in opto-electrical tracking servo system,it raises system type and improved the tracking precision.A cubic tracking control which made a V type system is designed.The tracking precision of a servo system on the cubic tracking control reaches 1’,which is 30 times higher than that of a PI control when the target moves at a maximum rate of 50(°)/s angular velocity with a maximum of 30(°)/s~2 angular acceleration.更多还原
