摘　　要：通过计算机控制系统将物理模型和数学模型两部分耦合在一起 .该控制系统有两条控制回路 ,即流量控制回路和水位控制回路 .其中流量控制回路实现了物模和数模在耦合边界处水位和流量的交换 ;水位控制回路实现了入海口潮汐水位的模拟 .同时根据采样和控制的高精度要求 ,分别在软件和硬件中采取滤波措施 .试验结果表明 ,计算机控制系统实现了物理模型和数学模型的实时耦合 。A hybrid model consists of a physical model part and a mathematical model part, linked by a micro computer control system. The control system has two control loops, i.e. a flux control loop and a water level control loop. The flux control loop realizes the exchange between the water level value and flux value at the coupling boundary, and the water level control loop realizes tidal level simulation. To meet the high requirement of precision of sampling and control, some filtering measures are taken in software and hardware. The experimental results show that the micro computer control system realizes the real time coupling between the physical model and the mathematical model, and the requirement of precision can be satisfied.
