污水输送泵站的模糊控制及其仿真

Fuzzy Control and Simulation of Sewerage Pumping Station

污水泵站系统具有非线性、慢时变、滞后性等特点,采用常规的PID控制很难获得满意的控制效果。本文采用模糊控制来实现污水泵站的智能控制,模糊控制器不需要建立被控对象的精确数学模型,并且结构简单,具有良好的控制鲁棒性。通过仿真结果可以看出,模糊控制的控制策略能够在使目标水位恒定的情况下,实现系统控制,达到最小能耗和最少污染双重目标。

The sewage pumping station has the characteristics of nonlinear, time-varying and complex lag, so it is difficult to obtain satisfactory control using conventional PID control. In this paper, fuzzy control is used to achieve intelligent control of a sewage pumping station. Fuzzy controller needs not an accurate mathematical model of object creation, and the structure is simple and has good control robustness. The simulation results show that the fuzzy control strategy to control the water level constant targets in the case, the realization of system control, at least minimizing energy consumption and pollution-fold.
