摘　　要：以简单管系统为研究对象,建立了有压瞬变流限压控制反问题的最优控制数学模型.采用δ-摄动法并经过空间离散,将由拟线性偏微分方程控制的有压瞬变流系统转化为时间连续线性系统,从而使有压瞬变流限压控制反问题能应用时间连续系统最优控制理论来求解.With the simple pipe system taken as an object for study, a numerical model for optimal control was developed. By use of δ-perturbation method with spatial discretization, the hydraulic transient system controlled by quasilinear partial differential equation was converted to a time-continuous linear system, so that the inverse problem of hydraulic transients under limited pressure could be solved with the optimal control theory for time-continuous systems.
