matlab Transport Delay环节 怎么填写参数

The Variable Transport Delay block can be used to simulate a variable time delay. The block accepts two inputs: the first input is the signal that passes through the block; the second input is the time delay, as shown in this icon.
(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 curren
