【摘要】 以电阻炉的温度为控制对象,应用基于ARM7内核的LPC2114和μC／OS-Ⅱ操作系统,分析了传统的继电自整定方法并进行了智能化改进,设计了一种嵌入式PID自整定控制器。实际应用表明:相对于经典的PID控制器,该控制器稳定、可靠,解决了温控难点及现场控制参数调整困难的问题。更多还原

【Abstract】 Taking the temperture of the electric oven as an example, an embedded self-turning PID regulator is given. Based on the LPC2114 of the Advanced RISC Machine (ARM), the real-time kernel μC/OS -Ⅱ is embedded to the system.According to the analyzed results and the control rules, the conventional relay automatic tuning method is ameliorated intelligently. The experimental results show that the regulator is safe and more applicable than classical PID regulator for the temperature control and the adjustment of parameter.更多还原
