基于Simulink的水产养殖溶解氧监控系统

The Detection and Control System of Dissolved Oxygen in the Aquaculture Based on Simulink

在水产养殖中,水体的溶氧量对鱼类生长和发育有很大影响,很有必要对其进行监控。为了提高监控的效果,建立了水产养殖溶解氧监控系统的数学模型,利用Simulink软件设计了PID控制器,并利用该软件中的非线性控制设计模块优化了控制器的参数。系统仿真分析表明,系统稳定,且优化后系统的超调量很小,响应变快,能够得到较好的控制效果。通过对水产养殖溶解氧监控系统的建模与仿真,可以为分析该系统提供重要基础,同时在实际应用方面积累了经验。

In the aquaculture, the dissolved oxygen is very important to the fish growth. So it is necessary for us to detect and control the dissolved oxygen in water. For improving the detection and dontrol effection, the model of the detection and control system of dissolved oxygen in the aquaculture was made, and the PID controller was designed using Simulink software, and the conti＇ol parameter was optimized using Nonlinear Control Design Blockset in the software. After the system model was analyzed and optimized by the Simulink software, its stabilization is well, and its overshoot is lower., and its response is faster. Therefore the control effect is better. The system model is made and the system is simulaed, it is the foundation of researching and applying the system.
