摘要
由于大面积建筑中存在大量不同类型的房间和区域,且其结构复杂,导致对其室内空间温度控制精度降低。为了有效精准的控制大面积建筑室内环境恒温性,提出一种大面积建筑室内环境恒温性自整定比例-积分-微分(Proportion Integration Differentiation, PID)控制方法。通过分析温度控制系统在不同操作环节的特性,获取温度控制系统在温度单参量控制下的数学模型。将通过数学模型采集到的温度信号展开计算处理,并将优化后的PID算法应用于环境恒温性自整定PID控制中,使其一直稳定在目标温度上,实现对大面积建筑室内环境恒温性控制。通过实验分析证明,采用所提方法对大面积建筑室内环境恒温性自整定PID控制后,稳态误差低于3%,且响应速度快。
At present,the complex structures in dfferent types of rooms and areas in large-area buildings may reduce the accuracy of indoor temperature control.In order to effectively and accurately control the homeothermy of the large-area indoor environment,this article presented a method of self-tuning PID(Proportion Integration Differentiation)control for the homeothermy of the large-area indoor environment.By analyzing the characteristics of the temperature control system in dfferent operating stages,we obtained a mathematical model of the temperature control system under single parameter temperature control.Then,we calculated the temperature signal collected through the mathematical model.Moreover,we applied the optimized PID algorithm to the self-tuning PID control of environment homeothermy and kept it stable at the target temperature,thus achieving the homeothermy control of the indoor environment of large buildings.The following conclusions can be drawn from experimental analysis.The steady-state error is less than 3%and the response speed comes faster after the proposed method is applied to the homeothermy selftuning PID control of a large area indoor environment.
