Real-time tests with predefined sinusoidal and random signals

In the tests, sinusoidal signals with different frequency and amplitude and random signals with different scales are used to get the difference between command displacements and measured displacements. As the aim of the project is to calculate the time delay of the test quantitatively, no time delay compensation method used.本次测试中，采用不同频率与幅值的正弦信号（sinusoidal signals）以及不同尺度的随机信号（random signals），以获取指令位移与实测位移之间的差值。鉴于本项目旨在定量计算测试的时延（time delay），故未采用任何时延补偿方法（time delay compensation method）。
