摘要
利用分数阶PID控制方法,通过基本假设进行模型建立,进行了大棚室内的温度调节的控制研究.数值仿真方法分析并比较了传统PID控制器、模糊PID控制器以及分数阶PID控制器的控制效果.研究结果表明,分数阶PID控制器相对另外两种控制器具有更快的提高控制系统的自适应性和鲁棒性的优点.
A suitable temperature environment is imperative for crop growth in a greenhouse.The temperature controllers used widely at the present time are a rather complicated non-linear system.In a study reported in this paper,the fractional order PID control method was used to construct a model based on basic assumptions and to adjust the temperature in the greenhouse.Numerical simulation was made to compare the results of the traditional PID controller,the fuzzy PID controller and the fractional order PID controller.The results showed that the fractional order PID controller was able to enhance the auto-adaptation and robustness of the control system more rapidly than the other two kinds of PID controller.
