Multiple degree-of-freedom (DOF) vibration control systems are essential for precision control of a wide range of space-born structures as well as eartb-based systems. This paper s t d i e s the design and control problems of a class of multiple DOF vibration isolation systems Using the concept of a Stewart trpss and Stewart platform mechanism. A novel geometric arrangement of a Stewart Platform, called the "Cubic Configuration" is developed and used. A new design and analysis of actuators employing magnetostrictive material Terfend-D is presented.Robust adaptive iUter algorithms for active vibration control are formulated. Prototype hardware for a six degree-of-freedom active vibration isolation system with the "cubic configuration" of the Stewart Platform has been implemented and tested. About 30 dB of vibration attenuation is achieved in real-time experiments.

Existing pursuer-evader (PE) game algorithms do not provide good real-time solutions for situations with the following complexities: (1) multi-pursuer multi-evader, (2) multiple evaders with superior control resources such as higher speeds, and (3) jamming confrontation between pursuers and evaders. This paper introduces a real-time decentralized approach, in which decentralization strategy reduces computational complexity in multi-pursuer multievader situations, cooperative chasing strategy guarantees capture of some superior evaders, and min-max double-sided jamming confrontation provides optimal jamming-estimation strategies under adversarial noisy environments. Extensive simulations confirm the efficiency of this approach.
