中文摘要：

温室环境调控系统是一类具有离散设备控制和连续环境因子输入输出的混杂系统.传统温室控制算法大都没有考虑温室的混杂特性,采用系统建模与古典或现代控制算法控制温室环境系统,缺乏对中国温室实际情况设计控制器和分析系统的混杂特性.为此基于混杂自动机理论,结合实验温室的降温设备,设计了夏季温度混杂控制器,并分析其执行的非阻塞性和确定性.春季和夏季实验表明,该控制器能根据设定值合理及时地切换控制设备状态.此外,建立了夏季和冬季两种典型模式的控制器框架,通过分析2013年夏季至2014年夏季温室内日最低温度,得到切换两种模式的参考时间设定值,为实现温室周年连续控制提供设定参数,对实际生产控制具有指导意义.

英文摘要：

Due to the interaction between discrete on-off controls and continuous environmental factors, greenhouse temperature control systems can be regarded as a class of hybrid system. Most previous greenhouse control algorithms rely on an exquisite system model and classical or modern control theories, and fail to consider the actual conditions of greenhouses in China in their design of a controller and their system anaysis does not include the hybrid properties of the greenhouse. Based directly on the hybrid automata theory, a hybrid controller was designed for controlling the temperatures of experimental greenhouse in summer. The controller was shown to be non-blocking and deterministic in hybrid automata theory framework. Experiments were performed in the spring and summer of 2014, and the controller behaved reasonably and timely when events triggered state transitions. Further more, a controller framework containing two typical hybrid controller modes was established for winter and summer to meet the needs of continuous control all year round. And the referential time points for mode transitions were obtained by analyzing daily lowest teml3eraturs from 2013 to 2014.
