| 摘 要： | 针对电阻炉温度控制纯滞后、大惯性环节控制的特点,传统的PID控制可以获得较好的稳态响应特性,但控制上会造成较大的系统超调,无法满足控制精度.应用参考模型自适应方法设计控制器,分析并给出了系统的数学模型,用超稳定理论设计了参考模犁自适应PID控制系统,并给出白适应率.以ARM单片机为核心,设计并分析了电阻炉智能温度控制系统硬件电路,由K型热电偶和数字转换芯片MAX6675组成温度检测电路,采用固态继电器来作为温控元件,利用开关特性来控制电路的断开和接通炉温控制主电路.实验结果表明该控制系统超调量小,跟踪速度快,可靠性高,结构紧凑、工作稳定.

| Abstract: | Regarding to the characteristics of great inertia and dead time delay associated with the temperature control system of resistance furnace,the traditional PID control can obtain a better steady-state response characteristic.However,it might cause a greater overshoot and its control accuracy cannot meet the requirements.A model-reference self-adaptive control system with a given adaptive rate was developed using Popov criterion theory.The hardware of intelligent temperature controller based on ARM single-chi... |
