If unexpected disturbances act upon an open-loop system, or if its behavior is not completely understood, then the output will not behave precisely as expected.
如果有不期望的扰动作用在开环系统上，或者如果其行为不能完全掌握的话，则该系统的输出就不会完全如预期般动作。
Using this method, the oscillation modes and non-linear dynamic behavior of power systems subjected to large disturbances can be studied.
使用该方法，可以研究电力系统遭受大扰动后的振荡模式和非线性动态行为。
Results as the velocity shear increases to a certain extent, the small scale disturbances will exhibit chaotic behavior, which leads to the production of turbulent spots in local high shear regions.
结果在速度剪切度增大到一定程度时，将会出现小尺度扰动的混沌行为，它导致局部高剪切区中湍斑的产生。
A control system is designed to control the behavior (the time response) of a plant subject to commands or disturbances.
控制系统设计就是使装置在有指令信号或者干扰时有满意的行为(时域响应)。
