In continuous annealing process, strip tension is an important factor that decides whether the continuous annealing line could work steadily and promptly or not. However, the tension fluctuations are inevitable as the continuous annealing process requires accelerating and decelerating frequently. In this situation, the synchronous response of the roll-speed helps to reduce this type of tension fluctuations...
In the pulverizing system for an alumina sintering processes, the hot air temperature to dry the coal powder using the remaining heat for cooling clinker is low and varies frequently. This can easily causes either the coal powder over coarser or the decrease of the mill output. In this paper, an intelligent setting method for mill load is proposed and presented, which consists of an intelligent pre-setting...
The electro-fused magnesia furnace is one of the main equipments used to produce electro-fused magnesia which is high performance refractory. Due to the multivariable, strong nonlinearity and coupling among the variables, strongly random disturbances of the fused magnesia production process, it is generally difficult or insufficient to only use one independent method to achieve satisfactory control...
In this paper, we investigate a novel adaptive design approach for nonlinear systems as an exploration of the new challenging topic on dealing with both parametric and nonparametric internal uncertainties in adaptive control of discrete-time nonlinear systems. The existence of both two kinds of uncertainties makes it very difficult or even impossible to apply the traditional recursive identification...
With ever increased needs for an improved product quality, production efficiency, and cost in today's globalized world market, advanced process control should not only realize the accuracy of each control loops, but also has the ability to achieve an optimization control of production indices that are closely related to the improved product quality, enhanced production efficiency and reduced consumption...
For complex industrial processes with strong couplings, high nonlinearities and uncertainties, conventional proportional-integral-differential (PID) control alone in distributed control systems (DCS) cannot achieve satisfactory performances. To deal with such problems, a nonlinear intelligent decoupling PID control strategy is developed, which can be easily implemented in DCS. The control system is...
