摘　　要：针对孵化系统具有强耦合、强干扰、大滞后的特点,提出一种混合智能控制算法。前级控制采用前馈补偿解耦控制算法以消除系统主要控制参数的耦合关系,后级控制根据被控制对象工况的不同,选用模糊免疫PID控制算法或模糊控制算法,实现了孵化过程中温度、湿度和含氧量的混合智能控制。实际运行结果验证了该控制算法的有效性。For an incubation control system, which is multi-variable, strongly coupled, disturbed, and lagged largely, a hybrid intelligent control algorithm was proposed. The coupling of main parameters was decoupled by the former control, which used feed-forward decoupling algorithm. According to the difference of technological condition, the fuzzy-immune PID control algorithm or fuzzy control algorithm was selected subsequently. The temperature, humidity and oxygen content were controlled well by the hybrid intelligent control algorithm. The factual running results proved that the control algorithm of the incubation system is effective.
