摘　　要：针对加热炉温度控制系统控制器参数不易选择的问题,提出一种分数阶自适应PID串级控制方法实现控制器参数自动调整。首先以分数阶PID控制器分别作为温度主控制器和燃气流量控制器,实现加热炉串级温度控制;其次应用自适应理论对控制器进行改进,设计了自适应分数阶PID控制器。最后通过数值仿真,验证了所设计控制系统对加热炉温度控制的有效性和可行性。Considering the difficulty in choosing controller parameters PID of the heating furnace temperature control system, an adaptive fractional order temperature cascade control for auto-regulation of the controller parameters was proposed. In which, having the fractional order PID controller taken as the main temperature controller and the gas flow controller to realize cascade temperature control of the heating furnace temperature, and then, having the adaptive theory adopted to improve the controller and design an adaptive fractional order PID controller. Numerical simulation verifies both effectiveness and feasibility of the designed control system for the temperature control of the heating furnace.
