Based on the 1st order cnoidal wave theory, the wave diffraction around the pier group inshallow water is studied in this paper. The formulas for calculating the nonlinear wave forces are also presented here. In order to verify the theoretical results, model tests are conducted in the wave flume in The State Key Laboratory of Coastal and Offshore Engineering located in Dalian university of Technology. The range of the wave parameters in the experiments is characteristic wave period T g/d^(1/2) = 8.08- 22.86, characteristic wave height H/ d= 0.1 ~ 0.45. The results obtained from the experiments agree with the theoretical results quite well. It is shown that, in shallow water the nonlinear wave forces acting on a pier group are greater than those calculated by linear wave theory, the value of increment in wave force increases with the increases of the nonlinearity of the wave. In the wave range studied in this paper, the nonlinear wave force can reach over 4 times the force calculatecd by linear wave theory. Thus, it is suggested that, when Tg / d^(1/2)> 8, the wave force on the piers in the pier group in shallow water should be calculated by using the cnoidal wave theory.

第24届中国控制与决策会议

作者： Haobo Kang, Hongjun Ma, Guanghong Yang College of Information Science and Engineering, Northeastern university, Shenyang, 110819, P. R. china

This paper deals with active fault tolerant con- troller design against time-varying actuator fault, aiming to improve the robustness, sensitivity of fault detection and the rapidity of whole diagnosis and compensation procedure. A high-gain observer technique is developed to design a residual signal with the estimation error of system states and the derivatives of system output. Then a reconfiguration controller is directly constructed based on the fault information from diagnosis procedure. A qualitative relation is derived to connect the robustness, rapidity and sensitivity of the proposed fault diagnosis scheme with the observe parameters. By prescribing the observer/controller parameters, the set of detectable faults, the time of detection and compensation and the bound of the closed-system signals are quantified. Finally, the theoretical results are illustrated by a simulation example of surface-mounted permanent magnet synchronous motors （PMSM）.
