摘要

环境因子对温室内植物的生长有影响，因此研究温室内环境因子的变化具有重要意义。本文分析了这种情况下的温湿度动态数学模型。温室内温湿度的变化不是简单的线性过程，而是复杂的非线性过程。采用非线性理论和方法对控制器参数进行分析，以满足最优的二次型性能指标。在MATLAB2008a中进行仿真，验证了该控制器的合理性和可行性。

Simulation on Temperature and Humidity Nonlinear Controller of Greenhouses

Environmental factors have effects on the growth of the plants in greenhouse, so it is significant to research the changes of environmental factors in greenhouse. The dynamic mathematical model about temperature and humidity of this situation is analyzed in this paper. The changes of temperature and humidity in greenhouse are not the simple linear process but the complicated nonlinear process. The nonlinear theory and method are used to analyze controller's parameters in order to meet the optimal quadratic performance indexes. The controller's rationality and feasibility are proved by simulating in MATLAB2008a.
