| 5. | 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。 |
| 6. | We take the peak current controlled dc / dc boost converter as an example . we compare and analyze power spectrum of input inductance current quantitatively of chaotic operation and periodic operation of converter . the computer simulation results demonstrate that power spectrum of input current has lower peak of power spectrum of chaotic operation than it of periodic operation , and then emi level is reduced 以一个峰值电流控制dc dcboost型变换器为研究对象,在分析电路混沌现象的基础上,分别对该电路工作于混沌和周期两种状态下的输入电流频谱进行了定量分析对比,证实了在相同输出电压条件下,工作于混沌状态下电路输入电流的频谱与工作于周期状态下电路输入电流的频谱相比,频谱峰值减小,具有降低emi水平的效果。 |
