| 中文摘要: |
| 本文研究了调水工程调节闸门 （阀门） 特性的动态系统辨识原理及方法。提出了闸门特性动态系统辨识的数学模型，通过数学变换将阀门非线性特性数学模型转换为线性模型，然后应用最小二乘法进行系统辨识，以便克服水力测量动态误差的影响。最后利用实测数据验证所提理论和方法的可行性和实用性。 |
| 英文摘要: |
| The principle and method for dynamic system identification of regulation gate（valve）characteristics in water diversion projects were studied. The mathematical model of the dynamic system identification of the gate characteristics was suggested. At first，the nonlinear mathematical model of the gate characteristics was converted to the proposed linear model by mathematical transformation，and then the least-square method was used to overcome the influence of measurement random error in identification. Based on the
measured data in laboratory，the validity of the proposed theory and method was verified. |
