| 摘 要： | 提出了具有对负荷变化前馈补偿的过热汽温系统预测函数控制策略，控制算法简单，易于工程实现，具有很高的实际应用价值。仿真结果表明，采用该新型控制策略的系统的动态品质明显优于采用PID串级控制策略的系统，而且系统克服负荷扰动的能力比采用PID串联控制策略和未加对负荷变化前馈补偿的PFC－PID串联控制策略的系统有了明显的提高。

| Abstract: | Predictive functional control strategy with feedforward compensation f or load fluctuation is provided in superheated steam temperature system. The alg orithm of the strategy is simple, and the strategy is easy to be realized in com puter or decentralized control system(DCS), therefore it has hopeful application prospect. Many computer simulation results show that the advanced control stra tegy has more favorable dynamic characteristic than PID cascade control strategy in superheated steam temperature system, and better load disturbance rejection than PID cascade control strategy and PFC-PID cascade control strategy without f eedforward compensation for load fluctuation. |
