摘要
煤矿电力系统是一种比较复杂的非线性系统,在一定条件下可能发生混沌振荡,会严重影响煤矿的安全运行。针对出现的混沌振荡,采用改进延时反馈控制方法进行抑制,其中反馈增益K采用梯度下降法进行调整,即用量子粒子群方法优化控制器的各个权系数,将混沌振荡稳定到平衡点上以达到消除混沌振荡的目的。通过仿真试验证明了这种方法的有效性。
Coal mine power system is a complex nonlinear system, under certain conditions, the chaotic oscillation may occur, which can seriously affect the safe operation of coal mine. For the chaotic oscillation, the improved time delay feedback control method was adopted, and the feedback gain K was adjusted by gradient descent method, the quantum particle swarm optimization was used to optimize the weights of the controller, and the chaotic oscillation was stabilized to the equilibrium point. The validity of this method was proved by simulation experiments.
