基于Simulink/VRML的渠道运行控制系统计算机仿真

Computer simulation of canal operation control system according to Simulink/VRML

从渠道运行的状态方程组出发,对控制方程组进行了离散化、线性化,从而得出了以闸门开度为控制变量,以水流深度和流量为状态变量的状态方程,并建立渠道运行系统模型,由此获得系统的Simulink模型(仿真模型)进行仿真分析,然后使用VR工具箱建立了一个相关的虚拟场景,并通过该工具箱的Simulink接口将渠道运行控制系统Simulink模型与该虚拟世界建立关联,从而利用Simulink模型产生的信号数据控制和操纵虚拟世界中渠道的运行控制.

The control equations are discretized and linearized by analyzing the canal operation equation; and a state equation in which the control variable is the gate opening,and state variables are water depth and discharge,is obtained,and then the canal operation system model is established.So that the Simulink models of the system for simulation analysis are obtained; and then a virtual scene is established by using VR toolbox.Then the relation between the Simulink models of the canal operation control system and the virtual scene is established by using the Simulink interface of the VR toolbox.Thus,the signal data which produced by Simulink models can be used to control and manipulate the operation of the canal in the virtual world.
