A time-optimal aircraft-following model is introduced to address air traffic flow interference by velocity reduction. The objective function is set up as minimizing the recovery time during which the separation minima are not infringed and the separation of the air traffic flow returns to the initial separation at the terminal time. Pontryagin’s minimum principle is used to solve the optimum aircraft-following...
The dynamic behaviors of flotation are hardly described using accurate mathematical models because of complex mechanisms, strong nonlinearities and uncertainties. The flotation reagent optimal control is difficult to be determined with conventional control method. According to this, combining modeling and control, an intelligent control software for flotation reagent process is researched and developed...
In the flotation process, the concentrate grade and the tailing grade are crucial technical indices which reflect the product quality and efficiency. Such technical indices have close relationship with the reagent feeding, the air flowrate and the pulp level. There are strong nonlinearity and uncertainties in dynamic behavior, which can hardly be described using any accurate mathematical model. The...
