(仿真的是一个变化的时间延时；这个模块需要两个输入，一个是输入信号，一个是是建延时)
The Maximum delay parameter defines the largest value the time delay input can have. The block clips values of the delay that exceed this value. The Maximum delay must be greater than or equal to zero. If the time delay becomes negative, the block clips it to zero and issues a warning message.（最大延时是指输入信号中的延时可达到的最大值；当超过设定的最大值时，这个模块将自动剪除；最大延时应该为非负数；如果时间延时为负的话，此模块将自动将其设为0并给出一个警告信息）
During the simulation, the block stores time and input value pairs in an internal buffer. At the start of the simulation, the block outputs the Initial input parameter until the simulation time exceeds the time delay input. Then, at each simulation step the block outputs the signal at the time that corresponds to the current simulation time minus the delay time.
在仿真时，此模块将在内部缓冲区中存储时间和输入值。仿真初期，此模块将输出初始输入参数。直到仿真时间超过延时时间时，此模块才输入（仿真时间-延时时间）处对应的值
When output is required at a time that does not correspond to the times of the stored input values, the block interpolates（插入） linearly between points. If the time delay is smaller than the step size, the block extrapolates（推断，推算） an output point. This can result in less accurate results. The block cannot use the current input to calculate its output value because the block does not have direct feedthrough（馈穿） at this port. To illustrate this point, consider a fixed-step simulation with a step size of 1 and the current time at t = 5. If the delay is 0.5, the block needs to generate a point at t = 4.5. Because the most recent stored time value is at t = 4, the block performs forward extrapolation.
The Variable Transport Delay block does not interpolate discrete signals. Instead, it returns the discrete value at t - tdelay.
Data Type Support
A Variable Transport Delay block accepts and outputs real signals of type double.
Parameters and Dialog Box
Maximum delay
The maximum value of the time delay input. The value cannot be negative. The default is 10.
Initial input
The output generated by the block until the simulation time first exceeds the time delay input. The default is 0.
Buffer size
The number of points the block can store. The default is 1024.
Pade order (for linearization)
The order of the Pade approximation for linearization routines. The default value is 0, which results in a unity gain with no dynamic states. Setting the order to a positive integer n adds nstates to your model, but results in a more accurate linear model of the transport delay.
Direct feedthrough of input ring linearization
Causes the block to output its input ring linearization and trim. This sets the block's mode to direct feedthrough.
Characteristics
Direct Feedthrough
Yes, of the time delay (second) input
Sample Time
Continuous
Scalar Expansion
Of input and all parameters except Buffer size
Dimensionalized
Yes
Zero Crossing
No
