摘　　要：为了实现对注汽锅炉干度的高质量控制,设计了一个基于模糊预测控制的干度控制系统,该系统通过对历史数据的自适应学习获得初始预测模型,并采用误差反向传播学习算法对模型参数进行优化,然后根据模型输出得出控制律,实现对干度的调节,因而具有较强的鲁棒性和自适应能力。实际应用表明,系统具有良好的控制效果。To implement the high-quality control of dryness, a dryness control system based on fuzzy predictive control technique was designed. It achieved original predictive model by adaptive learning from historical data and adaptively optimized its parameters by error back-propagation training algorithm, and then, derived the control law from the output of predictive model, thus, this system was provided with relatively strong robusticity and self-learning capability. Application showed that this system had an excellent control effect.
