摘　　要：根据已有的跳汰知识和规则,以及试验得到的跳汰周期、风阀参数、低压风压对液面脉动高度和床层松散度影响规律,设计了柔性空气室跳汰机风阀控制系统的专家知识库;采用前馈-反馈控制策略,以床层松散度为被控变量、液面高度为干扰变量,设计了基于专家控制器的柔性空气室模型跳汰机风阀控制系统。Expert knowledge database for the air-valve control system of the flexible air chamber jig was designed based on existing jig knowledge and rules, as well as the influence laws obtained from tests of jigging cycle, air-valve parameters and low wind pressure on the pulsation height of liquid level and the bed looseness. In addition, air-valve control system of flexible air chamber jig model was designed based on the expert controller by using feedforward-feedback control strategy and taking bed looseness as controlled object and lkluid height as interference variable
