| 摘 要： | 根据渠道输水的实际运行特点,提出了步进式PID渠道输水控制模型。在步进式PID渠道输水控制过程中,目标水位不是一次设定的静态水位,而是动态的,多次使输入指令一步一步的逼近所要求的最终目标水位,步进PID将使渠道输水更稳定,且响应速度可控制,有简单实用、可控性强的特点。仿真结果表明,较常规PID,步进式PID控制渠道输水,水位波动小,超调量小,较适合明渠输水控制的实际运行情况。

| Abstract: | This paper presents a step PID control method for canal flow according to the actual canal-flow operation.In the step PID canal control process,it is not set water level goal once time static,but set many temp goal that approach final goal step by step.This can control the water drop speed,and make the flow in canal steady.The Step-PID has the characteristics of simple,better controllability and operability.The simulations show that the water fluctuation and overshoot are smaller using Step-PID than using general PID control method.The method is suitable to open channel flow. |
