摘　　要：船载大型测控天线伺服系统的最内环是伺服驱动分系统,是整个伺服系统的设计关键。从硬件设计出发,系统综合运用四象限运行的思想设计了可控硅整流系统整流放大系统,设计了三相零式反并联整流电路,实现了伺服驱动装置可逆,可调稳态变速运行。采用环流抑制技术解决了晶闸管整流带来的缺陷,实现了对环流、谐波的有效抑制。为了消除齿轮间隙,采用双传动链设计方案。多次实践检验证明了该控制策略具备优越的控制性能,雷达跟踪快速稳定。Servo drive system Large shipbased is the inner ring of TTC antenna servo system,which is the key of the servo system design.Starting from the hardware design,Using the idea of four quadrant operation,This paper designed the silicon-controlled rectifier amplification system.By zero type three-phase rectifier circuit in parallel,the servo drive device is reversible,adjustable steady speed system.We solved the thyristor rectification of defects,implements the effective circulation,harmonic suppression by adopting circulation suppression technology.In order to eliminate the gear clearance,we adopt double transmission chain design.Simulation and practice show that the control strategy has excellent control performance,radar tracking stability quickly.
