However, this advantage is more than outweighed by the disadvantages of open-loop control and the inherent advantages of feedback systems.

然而，这一优点比不上开环控制的缺点和反馈系统的固有优点。

The institution of all the humping speed control systems basically depends upon open loop control which restricts the character of speed regulating and random adaptability to the circumstances.

现行各种制式的驼峰速度控制系统，都基本属开环控制，限制了速度调整的品质和当外界因素变化时的随机适应能力。

An internal model control strategy is proposed to a class of open loop stable nonlinear systems described by fuzzy neural networks.

针对一类开环稳定的非线性系统，提出了一种基于模糊神经网络的非线性内模控制方案。
