A tide simulating system is developed by using computer tocalculate and control the amount of water entering into and discharging from an experimental water basin.The composition,operation principle and main performance index of this system are introduced in this paper.%该系统根据要模拟的目标潮位曲线,利用计算机计算出控制水槽瞬时进出水量及尾门高度变化的时间信号,依此对多功能水槽的尾门运行及进出水量进行实时控制,以达到模拟目标曲线的目的。
