This paper presents a two-level controller based on neural network for wastewater treatment process. Predictive optimal control scheme using neural network is applied in the upper level control unit. The optimization unit is designed to generate trajectories of oxygen concentration and heterotrophic concentration. A feed-forward neural network is employed as prediction model. The gradient descent...
Coke oven heating process in coking production is a synthetic process, whose product key index, i.e. flue temperature, is hard to measure online, and the optimal control of such process is very difficult. Based on analysis of its dynamic characteristics and manual operation mode, a multivariable intelligent optimal control method is developed, combining intelligent method, feedforward control and...
