摘　　要：针对恒温培养箱中温度控制对象的时滞以及模型参数不确定的特性,提出了一种温度模糊控制方法。该方法不需要精确的系统模型,并克服了对象延迟滞后的特性。介绍了温度模糊控制器的设计,给出了系统实现电路,并通过Matlab进行了仿真。实验结果表明,该方法控制精度高、响应快,能满足恒温培养箱温度控制的要求。Aiming at the characteristics of long time delay and model parameters uncertainty of temperature control in thermostat incubator, a fuzzy control method was proposed. Based on this method, the object＇s characteristics of long time delay was overcome without accurate system model. The design of temperature fuzzy controller was introduced. Furthermore, system circuit of temperature control was given, and the simulation based on Matlab was done. The experiment result shows that the method has high precision and rapid responses. It can satisfy demands of temperature control of thermostat incubator.
