基于电加热炉的温度控制策略

在实际情况中，自适应控制比较难以实现，故很少出现比较准确的自适应控制。取电加热炉为实验对象，通过对电加热炉温度实施PID控制并最终达到稳定的过程中，采用实时辨识模型参数的闭环辨识策略，进而根据辨识结果实时调整PID参数，实现自适应控制。运行结果表明这一策略比常规PID控制效果要好。对于实际情况的自适应控制设计，具有一定的参考价值。

Research on temperature control strategy of electric heating stove

In practical situation, self-adaptive control is hard to realize, and therefore accurate adaptive control is few. Taking electric heating stove as the experimental object, during the process of implementing PID control of the temperature of electrical heating stove and ultimately reaching a stable state, a closed-loop recognition strategy for real-time recognizing the model parameters was adopted, and then the PID parameters based on the recognition results were adjusted simultaneously to realize self-adaptive control. The running result indicates that effect of this strategy is better than that of other normal PID control. For practical self-adaptive control, the strategy proposed has a certain practical reference value.
