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。 According to the existing knowledge and rules of jigging, the influence of the jig cycle, the parameters of the damper and the pressure of the low pressure on the fluctuation of the liquid level and the bed looseness, a flexible air chamber jig valve control system The expert knowledge base is adopted. By using the feedforward-feedback control strategy, the control system of flexible air chamber model jig valve is designed based on the expert controller with the bed loose degree as the controlled variable and the liquid level as the disturbance variable.
