时间离散化 meaning in Chinese
time discretization
Examples
- ( 3 ) we bring bdf method of order two forward as time discrete method for the two - dimension three - temperature heat conduction equations
( 3 )提出使用二阶bdf方法作为二维三温热传导方程的时间离散化方法。 - Comparing numerical character of above two models , it shows that the variance of atmosphere motion must be modified so the time step used in numeric simulation has no effect on numerical character of chaff clouds
对数值仿真模型的分析表明必须对大气的运动方差进行时间离散化补偿，进行离散化补偿后箔条云团的数字特征不受模拟时时间步长的影响。 - Hence analysis and design of nonlinear sampled - data systems has been , in recent years , a subject of growing interest in the international community of control research . when a continuous - time plant is controlled using a digitally implemented controller , it is often faced that a continuous - time plant is transformed into its equivalent discrete - time model . a digital controller is usually designed on the base of approximate discrete - time models of the continuous - time nonlinear systems because it is difficult to obtain the closed form of the exact discrete - time model for nonlinear control systems
利用计算机等一类离散控制装置来控制连续时间的受控对象时，都会遇到把连续时间系统化为等价的离散时间系统的问题，通过采样器和保持器来实现离散时间的采样控制，对于非线性连续受控系统，由于连续系统的时间离散化后一般得不到其等价的精确离散化模型表示的有限形式，实际上由其近似离散化模型代替来设计控制器，而近似会引起信号失真，那么基于近似离散化模型上设计的采样控制器，它是否同样对原连续受控系统有效
