As the restriction of the isolated feedback loop, the traditional primary-side control converters can not meet the requirements on fast dynamic response, high reliability and so on. 由于隔离反馈回路的限制,传统的原边控制模块在快速动态响应、高可靠性等方面难以满足要求。
The controller sampled signal and the control signal of the cut-off current control electronic ballast are isolated from a main loop by adopting the mode of electromagnetic coupling. 该电子镇流器所采用的保护控制电路简单、成本较低、工作安全可靠。
According to a number of isolated sub-tree caused by node failure, we set relation for isolated sub-tree to avoid loop. 针对节点故障造成数个孤立子树的情况,采用设定唯一上下游关系的方法,使各子树按顺序依次加入而避免了环路的产生。
Meanwhile, we analyse the impulse control problem of uncertain generalized composite system and its isolated subsystems. We give the norm bounds of system uncertainties which ensure the closed loop system impulse free. 同时分析了广义组合大系统及各个孤立子系统的脉冲控制问题,给出了其闭环系统无脉冲的不确定量的范数界。
