针对以机理建模为基础，采用PID策略的机炉协调系统在舰船运行期间无法平衡锅炉侧和汽机侧运行特性差异的问题，提出采用T-S模糊建模方法建立舰船协调系统模型，并基于该模型制定多模型预测控制加权策略，利用多模型广义预测控制方法设计协调控制器。仿真试验结果表明，基于多模型广义预测控制的舰船机炉协调控制系统响应速度更快、调节时间更短、稳定性更高、鲁棒性更强、综合控制效果更加优良，可有效提高蒸汽动力装置整体性能。
Aiming at the problem that the coordinated system based on mechanism modeling uses PID strategy cannot balance the differences in the operating characteristics of the boiler side and the steam turbine side during ship operation, a T-S fuzzy modeling method was proposed to establish a ship coordination system model,and based on the model, a multi-model predictive control weighting strategy was formulated, and uses a multi-model generalized predictive control method to design a coordinated controller. The results show that the coordinated control system based on the multi-model generalized predictive control has faster response speed, shorter adjustment time, higher stability, stronger robustness, better overall control effect, and can effectively improve the overall performance of the steam power plant.
