摘　　要：本文提出一种适于多水轮机系统的分散预测控制策略。分散控制结构能满足实际系统的物理要求,每一机组采用性能优良的水压转速联合预测控制器,并把因分散化所丢失的机组间的关联信息通过设计一扰动观测器加以补偿。通过对有水力联系的两水轮机组带孤立负荷时的仿真结果表明,这种分散预测控制器可使系统具有优良的动态响应过程。A decentralized predictive control scheme for multimachine system is presented in this paper. The decentralized structure meets the physical requiment of real system. Each hydraulic turbine uses water pressure and speed combined predictive comtroller, and the lost interconnection information caused by decentralization is compensated by a disturbance estimator. The simulation results for two machines with hydraulic interconnetion supplying an isolated load show the decentralized predictive controller carries out the good dynamic performance.
