摘　　要：针对浮选床液位这种大滞后、大惯性且难以建立精确的数学模型的控制对象,采用模糊自整定PID复合控制,根据浮选柱内的液位变化迅速由模糊控制策略调整自身的PID参数,从而快速稳定浮选床的液位值。结果表明,对于浮选床液位的控制,采用该算法的控制精度高,响应速度快,可满足浮选生产工艺过程中对浮选床液位的调节要求。For the control object such as liquid level of the flotation bed having hysteresis quality, great inertia and being hard to predicted precisely by building mathematics models, a self-ttming fuzzy PID compound control system was applied to adjust PID parameters rapidly according to the change of the liquid level of flotation bed, so as to stabilize the liquid level of the flotation bed quickly. The results showed： the method had high con- trol precision and rapid response speed in level control of the flotation bed, and could satisfy the requirements of adjusting liquid level of the flotation bed during flotation process.
