摘　　要：传统定型机在作业过程中热风箱温度控制系统存在惯性大和非线性等问题,为了保证织物加工后质量,根据定型机温度系统加热原理建立温度系统数学模型,提出基于模糊自适应PID调节原理的动态控制算法,通过分析模糊自适应PID控制原理,以PLC为控制器,依据现场热风箱内温度分析结果,对电加热器进行控制,进而保证现场温度在设定范围内。通过仿真结果表明,经过研究提出的模糊自适应PID对温度控制有较好效果,能够很好满足织物定型的工艺要求,具有一定的实用价值。Due to large inertia and non-linearity problems in the temperature control system of hot air box during the operation of traditional sizing machine, in order to ensure the quality of the fabric after processing, a mathematical model of temperature system was presented based on heating principle. A dynamic algorithm based on the PID tuning principle was proposed. Through analyzing the fuzzy adaptive PID control principle, taking PLC as the controller, according to the temperature analysis results in the hot air box, the electric heater was controlled to ensure that the temperature is within the specified limits. Simulation results showed that the fuzzy adaptive PID had an excellent effect on temperature control, could fully meet the process requirements and had some practical application.
