The paper states a control strategy implementing different control regulation in different phase ( coarse, fine and precision tuning) for enhancing the thermal efficiency of combustion of boiler. 文中提出分阶段(粗调、细调和精调)实施不同控制规则的控制方案,用于提高锅炉燃烧的热效率。
A new coarse tuning loop for a wide-band dual-loop frequency synthesizer is presented. 提出了一种用于宽带、双环路频率综合器的粗调环路结构。
The coarse tuning structure is composed of two digital modules, including a successive approximation register and a frequency comparator with a novel structure. 该粗调环路由数字电路设计实现,包含逐次逼近寄存器和新结构的频率比较单元两个模块。
Digital coarse tuning is defined as tracking phase while the analog fine tuning is defined as the acquisition phase. 数字粗调称为锁相环的跟踪阶段,而模拟细调称为捕获阶段。
