To deal with the problems, a supercavitating vehicle model proposed by Dzielski is employed as our research object. This model is converted into the Lure`s form by a series of system transforms. The sufficient condition for the global stability of the system is obtained by using the Nyquist diagram based on the circle criterion. The influence on the system performance produced by the pole-placement is analyzed. To improve the system performance, a switching control strategy is proposed, in which a nonlinear excitation is introduced to weaken the inherent nonlinearity.

The main contributions and innovations are as following:1 A new task decomposition model is proposed, which can decompose any maintenance task into task units, action units and motion elements. Based on virtual human`s kinematics model, an action classification criterion is provided, which is especially suited for maintenance simulation. Based on parametric modeling and encapsulation of maintenance actions, a Virtual Human's Action Database with a hierarchical architecture is designed and developed. Aiming at the reusability difficulty of captured motion data, a motion retargeting method based on path transformation is developed to reuse captured data, and several kinds of periodical ground locomotion actions are realized.2 In motion data compression, a key frame extraction algorithm based on kernel clustering method is proposed. Using Mercer kernel functions, motion data is mapped from the original space to the high-dimensional feature space, where the clustering process can be realized more efficiently. 3 A Petri Net-based locomotion-planning model is proposed to realize virtual human`s locomotion planning and walking control in dynamic environment.
