| 摘 要： | 针对电子膨胀阀的调节对象—空调制冷系统的工况时变性及非线性等特点,利用滑模变结构控制对被控对象的模型误差、对象参数的变化及外部干扰有极佳的不敏感性等优点,将滑模变结构控制方法引入电子膨胀阀控制系统中,并进行了滑模变结构控制器的设计与仿真,在仿真时还加入了系统的不确定性.结果表明该控制方案有效,而且系统具有很好鲁棒性.

| Abstract: | According to some flaws such as nolinear and uncertain working condition of air-condition refrigeration system,sliding mode control is adopted to electronic swelled valve by making full use of its non-sensitivity merit towards the mode error and the parameter changing as well as exterior disturbance.And the sliding mode controller is designed,with some uncertainty of model added to the system simulated.The simulation result indicates that the proposed control plan is effective,and the system also has good robustness. |
