研究了单区域空间的室内温度控制问题。在空调系统中，设定点的一个阶跃或一个脉冲或一个轻微的干扰都可能导致振荡。变风量（VAV）控制在空调系统中非常常见。空间的送风量可通过电动风门或风扇速度控制来控制。VAV系统被认为是狩猎的重要来源。为了探索变风量空调系统与蛇行运动之间的可能联系，将一个动态系统模型建立为具有时滞反馈的双线性模型（通过P或PI控制动作），并对稳定区域进行了参数分析。给出的结果显示了受设定值和控制参数选择影响的稳定区域。该分析旨在帮助我们调整比例积分微分（PID）控制器，以获得良好的控制性能。 单位:SICitation:ASHRAE Transactions，第115卷，pt。2009年1月1日，芝加哥

Indoor air temperature control of a single zone space is studied. In air-conditioning systems, a step or an impulse in setpoint or a slight disturbance, can lead to hunting. Variable air volume (VAV) control is very common in air-conditioning systems. The supply airflow rates to the space can be controlled by motorized dampers or by fan speed control. VAV systems are assumed to be an essential source of hunting. To explore the possible connection between VAV systems and hunting, a dynamic system model is formulated as a bilinear model with time-delayed feedback (by P or PI control actions), and a parametric analysis of the stability region is presented. Results are given that show the stability region affected by the selection of setpoint values and control parameters. This analysis is conducted to help us tune proportionalintegral- derivative (PID) controllers to achieve good control performance.Units: SI
