摘要
针对生长育肥猪的猪舍环境中温湿度变化具有非线性以及时变性的特点,设计一种双模糊自适应PID控制对其进行控制,通过与模糊PID控制在猪舍环境的温湿度控制进行控制效果的对比试验,试验结果表明,双模糊自适应PID控制把猪舍的温度控制在19℃~22℃之间,把猪舍环境的湿度控制在65%~75%的范围内,而模糊PID控制无论是在猪舍的温度控制还是湿度控制都存在较大的波动,温度的最大偏差为9℃,最大湿度偏差为15%,不利于生长育肥猪的生长。研究表明采用的双模糊控制理论的PID控制能够很好的满足猪舍环境中温湿度值,并将湿度很好的控制在65%~75%范围内,并且波动幅度不大。
Aiming at the challenges of non-linear and time-varying temperature and humidity changes in the piggery environment of growing and finishing pigs,a double fuzzy adaptive PID control was designed to control the temperature and humidity in the piggery environment with fuzzy PID control.A comparative test of the control effect was conducted.The test results show that the double fuzzy adaptive PID control controlled the temperature of the pig house between 19℃~22℃,and the humidity of the pig house environment in the range of 65%~75%.However,for the fuzzy PID,there were large fluctuations in temperature and humidity control in the piggery.The maximum temperature deviation was 9℃and the maximum humidity deviation was 15%,which was not conducive to the growth of fattening pigs.The research showed that the PID control using the double fuzzy control theory could sufficiently meet the humidity value in the piggery environment.and the humidity is well controlled in the range of 65%~75%,and the fluctuation is small.
