pH中和过程具有时滞、不确定、非线性特性,采用模糊自适应PID控制器能有效解决
这一问题。控制器的参数调整采用模糊调整规则,控制器的设计易于实现且具有很强的适应性和鲁棒性。仿真结果表明该控制器能对pH中和过程进行有效控制。

ABSTRACT : The pH neutralization process has the characteristics of lagging,
uncertainty and being nonlinear, a kind of fuzzy adaptive PID controller can solve
the problem effectively. The controller parameters are adjusted by using fuzzy
adjusting rules, so that the design of the controller is easy to be realized, and
it has strong adaptation and robustness. The result of the simulation shows that
the controller can control the pH neutralization process efficiently.
Keywords: sewage treatment;pH neutralization process;fuzzy adaptive PID
