摘要
温室温度系统是一个非线性、大时滞、大惯性的系统,很难建立精确的数学模型。针对这个问题设计了Mamdani控制器,并结合变论域的思想,实现了温室环境温度的有效控制。在Matlab中的Simulink环境下,对变论域Mamdani控制器的控制方法和常规PID控制进行仿真对比。仿真结果表明:运用变论域Mamdani控制器可以提高系统控制的精度和鲁棒性,实现对温室温度的精确控制。
Considering greenhouse temperature control system's nonlinearity,large delay and inertia and difficulty in establishing a precise mathematical model,the Mamdani controller with variable universe was designed for effective control of the greenhouse temperature. In Matlab's simulink environment,having Mamdani controller with variable universe compared with general PID controller shows that the Mamdani controller with variable universe can improve both control precision and robustness and realize the accurate control of the greenhouse temperature.
