Research on MTMP Structure Chlorine Dosing Decoupling Control

摘要

In this paper, multi tunnels multi pools (MTMP) structure chlorine dosing control method is studied. First residual-chlorine decay model is proposed, then MTMP chlorine dosing process model is acquired. After that, wavelet neural network is introduced to identify the α -th order inverse system so that pseudo-linearization system can be obtained. Then Time delay disturbance observer (DOB) control algorithm is designed for each decoupled subsystem, high performance and improved robustness are obtained. Simulation and application in tap-waterworks at Suzhou (China) shows that the algorithm is able to resist the model mismatch, disturbance and time delay, also the lower unit consumption of chlorine is obtained.
