蚕种催青室温度模糊控制

Temperature fuzzy control of the hatching of silkworm eggs

蚕种催青是桑蚕生产过程中最重要的环节.该过程中影响催青质量的主要因素是温度、湿度等参量,属于非线性、变参数、大延时对象,采用常规PID控制算法,其控制效果不理想.为此,设计了温度模糊控制.模糊控制的本质是非线性控制和自适应控制,对于参数波动和负载干扰的影响具有较强的鲁棒性.结合蚕种催青室的实际情况,以温度作为优先控制的环境因子,建立了模糊控制模型,给出了控制规则和模糊逻辑控制表,实现了对催青室温度的模糊控制,收到了较好的效果.

Hastening of the hatching of silkworm eggs is the most important work in silk production. The quality of hastening of the hatching of silkworm eggs has directly influenced the hatching rate, the tidy degree of hatching, and the production and quality. It is the key factor that controlling the parameters, such as temperature, and humidity which take an effect on quality during hastening of the hatching of silkworm eggs process, The essence of fuzzy control is a self-organizing control, which has high robust to the jiggle of input data and the influence from the load. In the paper, it introduced temperature as environmental factor of first control, Using the method of fuzzy control to control temperature of hatching room can gain a better effect.
