| 摘 要： | 针对被控对象存在的滞后、时变、非线性等特点，采用模糊控制与PID控制方式相结合的控制策略，设计了一种高精度温度控制算法，并以PIC18F258单片机为核心，实现了该控制方案。本控制方法在除氧器温度控制系统的应用中取得了良好的效果；文中使用MATLAB软件对PID控制、模糊PID控制分别进行了仿真研究，结果表明，参数模糊PID控制能满足调节时间短、超调量小且稳态误差在104±3℃内的控制要求。

| Abstract: | According to the characteristic of hysteresis, time-varying and non-linearization on controlled objects, a control strategy that combines the fuzzy with PID control is used to design a high precision temperature control algorithm with the chip PIC18F258 as the key part,and the control scheme is realized by this algorithm. The application of this scheme in the deaerator system achieves good effects. In this paper, the simulations to PID control and fuzzy PID control are carried out by using MATLAB. Finally,the simulation results show that the parametric fuzzy PID control can meet the requirements of the regulating time short,the overshoot little and the steady-error in the range of 104±3℃. |
