Abstract
PH neutralization process is composed of a complex and multivariable nonlinear coupling. This paper combines the fuzzy control and sliding mode control, and studying on the control of pH value and liquid level of pH neutralization process. On one hand, this approach simplifies the fuzzy control, on the other hand, it adjusts the universe of fuzzy control system by quantification scale factor changing adaptively and makes system control signals soften and reduces the chattering of sliding mode control. Here, quantification scale factor improves control accuracy of systems. The simulation results show that even a major change in operating point, the systems still have good anti-disturbance and strong robustness.
