【摘要】 在河工模型试验中,要复演天然河道水位的变化过程,模型尾部水位的控制尤为重要.根据河工模型试验要求,针对河工模型水位调整特点,设计了由PID控制器和参数自适应模糊PID控制器组成的变结构控制算法,可根据检测实际水位与要求水位的差别,调整尾门水位控制闸门的开闭速度及开闭度,既保证了水位调节的快速响应,也保证了水位控制的稳定性.更多还原

【Abstract】 The control of river model tail water lever is important for reviewing the change process of nature river water lever.Taking into the experiment requirements,combining with the characteristic of control to river model tail water lever,the paper designed a variable structure PID control algorithm composed of PID controller and parameter adaptive fuzzy PID controller.This algorithm can adjust the rate and degree of tail water lever gate,according to the contrast of real water lever and required water lever.The system provided rapid response velocity and water lever stability in river model experiment.更多还原
