In order to solve the safe operation problem for dynamic positioning vessel operating in rough sea after the failure of sensors, a method of fault-tolerant control for dynamic positioning ship was investigated. Based on the reconfiguration of virtual sensor control, a robust sliding mode of virtual sensor was proposed to implement fault-tolerant control. Lyapunov stability theory was applied to prove the stability of the system. The simulation results indicated that the ship continued to maintain the capability of positioning in the case of sensor failure. ©, 2014, The Editorial Board of Ship Building of China.

The Pressure Sensitive Paint (PSP) technique is one of the important pressure measurement techniques on model surface in wind tunnel test. This report presents that has tried to make the pressure sensitive paint in China, the automatization test data collection technique, the test data disposal technique, the application method of PSP technique, the comparison tests between PSP technique using PSP FOP-1 paint made in China and classic tap measurement technique on the wing, leading-edge flap, trailing-edge flap, aileron of airplane model.

The Pressure Sensitive Paint (PSP) technique is one of the important pressure measurement techniques on model surface in wind tunnel test. With the help of PSP technique it is possible to measure pressure of the complex or special model surface that is very difficult in virtue of pressure taps measurements. This report presents the application method of PSP technique, the comparison test results between PSP technique using two-component PSP made in China and classic tap measurement technique on the wing surface of airplane model, showed that the performance of two-component pressure sensitive paint made in china is better than the imported ones and can be substituted for them. The PSP technique used two-component pressure sensitive paint made in china can be used to model pressure testing. Source
