摘要本文介绍了一种带有开关执行器的人工气候室的建模和控制。室内的受控环境变量是温度、相对湿度和照明。首先通过非线性变换对系统进行解耦，并利用子空间方法辨识出系统的线性模型，进而提出了一种具有开关执行器的过程的模型预测控制策略。该控制器采用设定点过滤，以提供平稳的气候过渡。附真实的人工气候室的控制结果。
Abstract This article presents modelling and control of a climatic chamber with on/off actuators. Controlled environmental variables in the chamber are temperature, relative humidity and illumination. The system is first decoupled by nonlinear transformation and a linear model is identified using subspace methods; further, a model predictive control strategy for processes with on/off actuators is presented. The controller incorporates set-point filtering to deliver smooth climate transitions. The control results from a real climatic chamber are attached.
