摘　　要：家禽孵化是一个复杂的生物学过程,实现其自动控制水平有着重大意义.针对孵化系统是一个多变量、强耦合、大滞后的复杂动态系统,提出一种模糊免疫P ID控制方法,该方法根据模糊控制原理对P ID参数进行在线修改,利用生物免疫机理调整非线性函数,然后用免疫修正进一步调整P ID系统参数,使被控对象具有良好的性能,实现了家禽孵化设备中温度、湿度和含氧量的智能控制.系统投入运行表明,动态响应好,控制精度高,鲁棒性高,易于各种孵化的实现,从而提高了孵化率.It is important to realize automation of the fowl incubation which is a complex biological processing. Based on that incubation control system which is multivariable, strongly coupled, lag largely, a fuzzy-immune PID control method is proposed. Firstly, the fuzzy-immune PID controller adjusts main parameters according to fuzzy rules and adjusts nonlinear function according to immune correction. Secondly, the parameters of PID is tuned by using immune regulation mechanism, thus, it enable the object have a good performance and realized the intelligent control of temperature, humidity and oxygen content. The run of system indicate that, the system has such virtue of quick dynamic response, high control precision and strong robust, thus each kind of incubation can easily be realized and the incubation rate can be largely be enhanced.
