摘要
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.使用Matlab软件对PID控制、模糊PID控制分别进行了仿真研究,仿真结果表明参数模糊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.
A conrol strategy in combination ot fuzzy and PID conrol is employed to design high precision automatic temperature controlling algorithm with the chip PIC18F258 as the key part and the controlling method is realized. First, simulations of PID control and fuzzy PID control concerning their respective control quality are done by Matlab 6.5. Moreover, the simulation results show that its robustness is good, because effective control makes the regulating time short, the overshoot and the steady - error very little.
