【摘要】 对三渠段串联的运行过程及各渠段之间的相互作用进行了详细分析,给出了三渠段串联系统的求解流程图。以蓄量不变为控制目标,为提高系统灵敏度设计了PID控制器。利用MATLAB/SIMULINK动态仿真工具建立了模块化的三渠段串联系统的仿真模型,完成了参数选择,实现了系统运行的实时动态仿真。仿真结果表明该模型实现了蓄量不变的控制目标,并使系统获得了良好的动态性能。更多还原

【Abstract】 The moving process and the interactions among the canals in series are analyzed in detail,and the flow chart of solution is established and explained.A PID controller is designed to raise the sensitivity of the system.By using simulation tools of MATLAB/SIMULINK,the modularized simulation model of the system is built,the parameter selection is realized,and the real-time and dynamic simulation of canals’ moving process is implemented.The simulation results show that the aim of keeping a constant quantity of the water is realized and the dynamic performance of the system is good.更多还原
