超驰控制与自动调节运行安全

运行安全是自动控制系统设计是必须考虑的因素之一，而超驰控制则是保证设备安全的有效措施，为此，介绍超驰控制在自动调节系统中的作用，功能，应用实例，并建议在系统设计阶段把可以预见的异常工况纳入超驰控制之下，使系统和设备的安全有比较可靠的保障。

Override control and auto control operating safety

The operating safety is one of the most important factors when the automatic control system is designed, and override control is effective measure pledging the equipment safety operating. This article introduce the effects, function and application of override control in the automatic control system. This end, and abnormal operating mode suggesting in systems design stage can foresee below bringing into override control which makes the operating of system and equipment have a fairly more safe guarantee.
