Presents a control strategy for underactuated mechanical system: the acrobot example, which combines fuzzy control and linear quadratic control. The fuzzy controller designed for the upswing ensures that the energy of the acrobot increases with each swing. After the acrobot enters a neighborhood of the unstable straight up equilibrium position, a linear quadratic regulator is designed to balance it.

Dynamic fracture of explosion containment vessels(ECVs)subjected to internal blast loads is the foundation for conducting safety assessment and failure analysis of *** experiments were carried out to investigate dynamic fracture characteristics of cylindrical steel shells subjected to internal blast loadings at the *** elastic-plastic response of cylindrical steel shells was conducted through using nonlinear dynamic finite element(FEA)analysis code *** fracture mode and fracture mechanism of a cylindrical shell were specially studied through analysis of deformation,macrographs and meso-graphs of fracture surface and elastic-plastic *** results show that the axial direction fracture surface of the cylindrical steel shell exhibits a mixed ductile fracture mode with shearing dimple by micro-void *** ductility deformations appear and the shear bands form when the cylindrical steel shell expands under internal blast loading. The cylindrical steel shell preferentially fractures along the shear bands due to its softening *** fracture mechanism is that the shear bands tear under tensile circumferential *** shear bands and the tensile circumferential stress dominate the final fracture *** fracture mode is of the ductile fracture.

The medium -large caliber naval gun is still playing an important role in modern war. The development of highly automatic Shell Raising and Feeding System (SRFS) in the world has been briefly outlined. Several typical SRFS of medium-large caliber naval guns have been analyzed. A re-design of the system is introduced, in which systematic design method has been used to demonstrate its feasibility. The design goal of the system is to realize rapid shell feeding, with application to many types of shells, quick change of shell types , accurate and reliable feeding operation, simple mechanical structure and easy realization of shell withdrawing.

关键词： the medium-large caliber naval gun, shell raising and feeding system, systematic design method.

第二十七届中国控制会议

In the research project,the goal is to reduce PSD on acceleration of sprung mass by automatic control of active dampers in *** two-DOF vehicle suspension model,control strategies are being developed and tested in simulation *** acceleration of the sprung mass,dynamic tyre load between wheels and road and dynamic deflection between the sprung mass and the unsprung mass are determined as the evaluation targets of suspension *** control algorithm,which is called LMS adaptive control,makes it possible to reduce RMS on acceleration of sprung mass significantly. For LMS adaptive control suspension,compared with passive suspension,acceleration PSD of sprung mass acceleration under the road input model has all decreased largely as 8-10 times in high frequency resonance band or low frequency resonance band.
