Abstract:

For the optimization of slurry pH value control system to conduct a comprehensive control, the whole system run in the best state, an improved PID algorithm.The algorithm using single neuron with the advantages of adaptive, self-learning ability, after the neurons into the PID algorithm, the improved control system stability and control performance is poor;Combined with the characteristics of slurrypH value control system, designs the concrete process of the algorithm.In the end, both before and after using the improved algorithm for optimization problems are analyzed in the simulation, the results show that the single neuron adaptive PID algorithm has better optimization effect.
