矿井通风的H_∞优化控制

Ventilation Control in Mine Based on H_∞ Optimization Control

提出了基于H∞优化控制理论的矿井通风控制问题。首先建立了将主风流作为当前状态、主扇风机输出功率作为控制输入,并考虑实际井下环境干扰和瓦斯检测滞后的动态模型,然后对该模型进行了考虑控制成本的、以瓦斯检测输出作为反馈的H∞控制设计。仿真结果表明,矿井通风的H∞优化控制是一种既体现了技术优势,又兼顾了经济效益的整体优化策略。

A scheme of ventilation control in mine based on H_∞ optimization control technique was (presented.) A dynamic model with main air flow as current state and ouput power of main fan as control input for the system was built. And in the model, the environment interference and the detection lagging for gas in practices were taken in account. For the model, an H_∞ control strategy with output feedback from gas observers and consideration of control cost were given. The simulation result showed that it is one of the best strategies in the same field under the requirement of the optimization in both technology and economy.
