摘要

本文介绍了模糊控制和非线性估计在污水处理厂控制中的应用。这种生物过程是高度非线性的，由于不可测量的变量和输入干扰，其控制是一项具有挑战性的任务。模糊控制可以有效地减小不可测扰动的影响，但所使用的结构需要测量所有的状态变量。为了估计未测信号，提出了一种非线性估计器。最终的控制结构由非线性估计器和模糊控制组成。通过仿真验证了该方法的适用性。

Wastewater treatment plant control by combining fuzzy logic and nonlinear estimation

The paper presents the application of fuzzy control and nonlinear estimation to wastewater treatment plants. This biological process is highly nonlinear and its control is a challenging task due to unmeasured variables and input disturbances. Fuzzy control is quite efficient to reduce the effect of unmeasured disturbances, but the used structure requires the measurement of all the state variables. In order to estimate the unmeasured ones, a nonlinear estimator is proposed. The final control structure is composed by the nonlinear estimator and the fuzzy control. The applicability of the proposed approach is validated via simulations.
