poles and zeros meaning in English
极点与零点
Examples
- We will defer discussion of complex poles and zeros to a future article
我们会在其他文章中再谈复杂的极点和零点。 - Abstract : this paper developed time domain integral constraints on error response for siso feedback control systems caused by nominal plant ' s near cancellation of stable pole - zero near the j - axis . these integral constraints should be satisfied by any feedback control systems . these integral constraints give new insight into the inherent trade - offs . it will result in the settling time longer or the infinite norm of the error response larger when there are near cancellations of stable pole - zero near the j - axis . hence , when feedback control systems are designed , it is necessary to avoid the compensator ' s poles and zeros nearly cancelling the nominal ' s zeros and poles ( even if these poles and zeros are stable )
文摘:导出了单输入单输出反馈控制系统误差响应基于名义系统稳定的零、极点近似相消的时间域积分约束,此积分约束是任何反馈控制系统均应满足的.这一约束给出了单输入单输出反馈系统固有折中的新的观点.名义系统稳定的零、极点近似相消的存在导致反馈控制系统的调节时间延长或者误差响应的无穷范数变大.因此,在反馈控制系统设计中,尽量避免补偿器的零、极点与名义系统的极、零点近似相消(即使这些零、极点是稳定的) - The aircraft ' s longitudinal motion short period poles and long period zeros in right plan e may make the aircraft control system be not got by only using qft . so pole and zero assignment by state feedback is needed to change this circumstances and then qft is used to get the control system . simulink results are given to prove at the system meets the requirements .
飞机纵向运动方程的短周期和长周期的右半平面可能存在零极点对问题，这对飞机控制造成不利影响，直接利用定量反馈理论不能满足要求。本次论文首先进行短周期状态反馈极点配置，然后利用定量反馈来解决这个问题。通过仿真分析得到满意的结果。
