In view of the characteristics of redundant actuations,strong coupling,and nonlinearity,a modified proportional differential (PD) control strategy with feedforward compensation in the wire length coordinates is developed based on stiffness enhancement,and an optimal tension distribution is implemented for the enhancement of stiffness in lift,along-wind and pitching directions.

In the paper,the imitation study is made for some problems about tension distribution of unbroken cord ropes.

Therefore,a method of tension distribution and temperature compensation was proposed in this paper.

Referring to the theory of the modern air-combat, the thesis studies respectively the two key techniques of multi-target attacking game, which are multi-target sorting, optimization of fire distribution.

A mathematical model of the sensor optimal distribution is established based on maximum information gain criteria,taking identity and priority of target into account.

To confirm the project of regional water resource development in a reasonable way so as to promote relevantly the sustainable economic development,a multi-objective programming model is developed for the optimal distribution of water resource in Songyuan city in view of system engineering,according to the present situation of water resource and future goals.

The solution is made in two steps:getting economic unit commitment subjected to load constraints and obtaining optimal distribution of spinning reserve.
