闭环控制系统
闭环控制系统(closed-loop control system)的特点是系统被控对象的输出(被控制量)会反送回来影响控制器的输出，形成一个或多个闭环。闭环控制系统有正反馈和负反馈，若反馈信号与系 统给定值信号相反，则称为负反馈( Negative Feedback)，若极性相同，则称为正反馈，一般闭环控制系统均采用负反馈，又称负反馈控制系统。闭环控制系统的例子很多。比如人就是一个具有负反馈 的闭环控制系统，眼睛便是传感器，充当反馈，人体系统能通过不断的修正***作出各种正确的动作。如果没有眼睛，就没有了反馈回路，也就成了一个开环控制系统。另例，当一台真正的全自动洗衣机具有能连续检查衣物是否洗净，并在洗净之后能自动切断电源，它就是一个闭环控制系统。
