摘　　要：将蒸汽发生器的线性参数变化模型作为预测模型,设计H2/H∞多目标模型预测控制器.根据鲁棒模型预测控制算法,在线求解多目标优化问题获得控制器.求解时指定一个性能指标优化另一个性能指标,所设计的控制器为变增益控制器.仿真结果验证了此方法的可行性,与串级PID控制相比,具有更好的控制性能.The linear parameter-varying model of steam generator was considered as the prediction model to design the H2/H∞ model predictive controller.According to the model predictive control algorithm,solution of the gain-scheduled controller which was proposed in this paper was enforced by specifying one of performance indicators to optimize another online.The simulation results showed that the controller has better performance than that of the cascade PID.
