时间-比例控制器可以通过控制离散执行器的输出状态在开和关之间循环,达到和连续执行器一样的效果。在上面的示例中,控制器让执行器在50%的时间内处干“打开”状态,从而实现50%的控制效果。在下面示例中,控制器让执行器在3个循环周期内处于“打开”状态,之后的1个循环周期内处于“关闭”状态.从而实现75%的控制效果。 Time - Proportional controllers can achieve the same effect as continuous actuators by controlling the output state of discrete actuators to cycle between on and off. In the example above, the controller allows the actuator to go “on” within 50% of the time, resulting in a 50% control. In the following example, the controller has the actuator “on” for 3 cycles and the “off” for 1 cycle thereafter, resulting in 75% control.
