摘　　要：针对温度控制系统采用传统PID控制方法易出现响应速度慢、超调量大、控制精度低等问题,提出了一种基于积分分离模糊PID控制的改进方法.阐述了该方法的工作原理,设计了控制器参数,并结合温室温度控制系统对该方法以及传统PID、模糊PID进行了系统性能实验的对比分析.结果表明,采用该方法设计的温室温度控制系统,有响应速度更快、超调量更小和控制精度更高等优点,具有较强的工程应用价值.Taking into consideration the disadvantages of the traditional PID （proportional integral derivative） control method-low response speed, large overshoot and low control precision-for the temperature control system, the authors propose in this paper an improved control method, which is based on integral apart fuzzy PID. The working principles of this method are expounded, and the relative controller parameters are designed. A comparison was made of the traditional PID control, the fuzzy PID control and the proposed integral apart fuzzy PID control through an experiment with a greenhouse temperature control system, and the results indicated that the proposed integral apart fuzzy PID had faster response, smaller overshoot and higher control precision, thus showing promising potentials for engineering application.
