cycle movement meaning in English
周期性运动
Examples
- The " linear " hypothesis only can describe three kinds of economic movements , that is , convergence , divergence and the second cycle closed movement ; but ca n ' t illustrate every kind of cycle movements and chaos , which are frequently happened
其“线性”假定只能描述蛛网模型中的收敛、发散、 2个周期闭合3种运动类型，不能刻画最常出现的各种周期运动及混沌现象。 - The dynamic change and the stability of the generalized cobweb models such as model one are studied , including setting up the models and giving the economic meanings ; dynamic analysis on model one and proving that the price array produced by model one wo n ' t emerge above the third cycle movement and chaos ; stability analysis on model one and obtaining six theorems about the stability of equilibrium price . chapter four , analysis on some specialized cobweb models . this is the second key part of the thesis
主要研究了对形如模型( )的一般化蛛网模型的动态分析与稳定性问题，主要包括三个方面工作：一是建立模型并给出经济含义；二是对模型进行动态分析，证明了由模型( )所生成的价格系列在一定的条件下不会出现3以上周期运动和混沌现象；三是对模型进行稳定性分析，并得到模型( )关于均衡价格稳定的六个定理。 - A flight trajectory math model of an assumed cruise aircraft is built according to a simple blue print of the flight control system , with the foundation of a particular analysis of its kinematics and dynamics . a linear light - disturbed minor - cycled movement model and the transform function models are got through some simplifications
本文以某个虚构的巡航式飞行器的飞行控制系统为研究对象，首先讨论了一个简单的总体方案，然后根据此方案，在详细分析此飞行器运动学与动力学的基础上，建立了飞行器飞行仿真数学模型，并在允许的条件下进行简化得出了此飞行器线性化小扰动短周期运动模型与传递函数仿真模型。 - Then in allusion to biased momentum wheel system , based on classical control system a pid controller was design about pitching channel . according to specialty of roll - yawing channel , this paper discuss long - time cycle movement and short - time cycle movement . when design the control method of long - time cycle movement , whiff thruster is used to assistant the control system . when design the control method of short - time cycle movemen , in order to sovle the problem of coundn ’ t abtain the angular velocity signal , nonminimum phase controller advanced by terasaki is used
然后针对偏置动量飞轮系统,基于经典控制理论设计俯仰通道的pid控制律,根据滚动?偏航通道耦合的特点,分别讨论了由轨道角频率和章动频率引起的长周期运动和短周期运动。其中长周期运动控制律设计时,结合了喷气推力控制来辅助偏置动量控制;短周期运动控制中,为了解决不能获得角速度信号的问题,采用terasaki提出的非最小相位控制器进行控制。
