摘要
在固态下料系统的设计中,存在输入信号的波动和选取何种控制模型两个关键问题。对系统进行分析后,分别选择限幅和惯性两种数字滤波算法综合对该系统输入信号进行处理,处理后的信号能够较好地反映了系统当前的输入状态。选择模糊控制模型,实现了对控制对象的自动调节。生产实践表明,系统的抗扰动性能及精度完全满足生产要求。
There are two key problems in design of solid material feeding system, one is the fluctuation of input signals, the other is the control model selection. Through analysis of tire system, two types of digital filtering, i.e. inertia filtering and limit filtering are selected for input signal processing, the processed signals can well reflect current input status. Then fuzzy control model is selected to implement automatic regulation for controlled object. The production practice shows that the system offers high anti-interference capability and the accuracy meeting production requirements.
