摘要
针对中央空调系统的复杂性,提出一种将各传感器信号按能量意义进行集结的思想,进而将所集结的能量包作为系统的状态变量实施自动控制;给出了能量包和传感器信号间的函数构造实例;控制策略采用以稳态测量值所形成的能量包进行递推,以消除系统时滞因素的影响。应用实例表明,这一方法计算简单、物理意义清晰,控制效果十分出色。
A new idea is proposed to manage the complexity of the process control. The sensor＇ s signals in a complicated process system are collected into the energy pack under the sense of the energy transfer, and treat the energy pack as the state variable to design controller. An actual method is given for the function relation be- tween the energy pack and sensor＇ s signals. An iterative algorithm based on the energy pack which is formed by the steady measurements of sensors is employed to avoid the bad effect caused by the time delay. The practice shows that this approach is very simple and explicit in the sense of engineering, and the control result is excellent.
