摘要
针对闭环控制系统中当反馈回路信号极其微弱时暴露出的性能缺陷,通过电路结构和数学模型两种方法分析了微弱反馈回路信号对于闭环系统控的制稳定度和灵敏度的影响,提出了微小反馈信号时如何保持闭环控制稳定性和灵敏度的分级放大方法及参数设计。
With respect to performance deficiency exposed in the closed-loop control system when the feedback loop signal is extremely weak,in the two methods of circuit structure and mathematical model,this paper analyzes the influence of weak feedback loop signal upon the stability and sensitivity of the closed-loop control system,and proposes a stage amplification method and parameter design to maintain the stability and sensitivity of the closed-loop control.
