Reverse Osmosis Water System Based on Sparrow Search Improved Active Disturbance Rejection Controller

In this paper, a reverse osmosis water making system is designed to solve the problem that the conductivity of produced water is unstable due to the change in ambient temperature and the fluctuation of water quality. A unique double pump double film double stage reverse osmosis process was designed and the active disturbance rejection controller was introduced to realize the effective combination of booster pump and reverse osmosis membrane. Aiming at the problems of high complexity, long time, and expe-rience dependence in the process of controller parameter adjustment, the sparrow search algorithm is used to realize automatic parameter optimization. Through the simulation of the system, the results show that the reverse osmosis water system shows good adaptability and anti-interference performance in dealing with external interference.
