【摘要】 当采用计算机在线控制时,控制器由微处理机软件来实现,必须将渠道连续时间系统模型离散化。在渠道连续时间系统模型的基础上,综合考虑水力学和控制学的要求,采用适当的采样器和保持器,推导出渠道离散时间系统模型。将最优控制理论应用到渠道离散系统运行管理中设计出最优控制器,通过模拟仿真,验证所建立的渠道运行控制理论和设计方法是可行的。更多还原

【Abstract】 When computer is applied to the canal operating control, canal continuous-time model must be dispersed. According to the hydraulics and the control, the canal discrete-time model with proper sampler and cage is established on the basis of canal continuous-time system model. Applying optimal control theory to canal control system, the optimal controller was worked out. By simulating operation of canal control system, the validity of established theory and design method on canal operating control were tested.更多还原
