| 摘 要： | 温室天窗温度系统可以看作是一个混杂动态系统,由于天窗的动作与控制对象温度之间的关系可以通过温度状态的值和操作约束来确定。在建立温室温度系统机理模型的基础上,将对于温度控制的操作约束和温室天窗开关动作等以命题逻辑表述,并将这些命题逻辑转化为混合整数线性不等式,然后引入辅助变量,将辅助变量和不等式约束统一到温度系统的离散状态空间模型中,构成了温室天窗温度的混杂逻辑动态模型。仿真试验表明,所建立的温度混合逻辑动态模型能较好模拟和控制室内温度。

| Abstract: | The ventilation window temperature system in a greenhouse can be regarded as one of the hybrid dynamical systems since the interactive dynamics between the actions of ventilation window and the output of the control system (temperature) according to the value of inside temperature and operational constrains. The physical models of the temperature system were made. Secondly,the constrained operations for temperature control and the on-off statuses of the window were transferred into propositional calculus; t... |
