摘要
提出了基于对角解耦的温室大棚温湿度预估PI控制的系统设计方案,采用AT89S51单片机、温度传感器AD590、湿度传感器IH3605,设计了一个温室大棚温湿度对角解耦控制系统,实现温室大棚温湿度的实时控制与测量。经实验对比测试,系统温度绝对误差可控制在0.30℃、湿度绝对误差可控制在2%RH范围内,满足了温室大棚温湿度高精度控制要求。
The system of decoupling and PI estimating controller adopted AT89S51 mieroeontroller, AD590 to examine temperature and IH3605 to examine humidity. The system would detect and control actual temperature and humidity. The actual results show the temperature accuracy could be controlled within 0.30% and humidity accuracy could be controlled within 2%RH and good effects of temperature achieved by this controller.
