In this paper,we have presented an autonomous guidance strategy based on optimal states feedback technology.First,by utilizing classical Gauss motion equations,we derived the three separate control laws,which could maximize the time rate of change of a desired orbital element.

首先利用传统Gauss型运动方程，推导出三个轨道根数增大最快的独立控制律；然后根据当前根数与目标值的偏差量对独立控制律进行加权组合；最后为高效可靠地获得最优制导律，采用一种遗传算法和逐次二次规划相结合的混合方法对权重进行了优化。

First, by utilizing classical Gauss motion equations, we derived the three separate control laws, which could maximize the time rate of change of a desired orbital element. Then, the separate control laws were blended based on the deficit between current and target value of orbital state. Finally, to obtain the optimal guidance law effectively and reliably, a hybrid method combining genetic algorithm with sequential quadratic programming was used to optimize the weight values.

That daily turnover in the currency futures is higher relative to open interest (the number of futures contracts that are open at the end of a session) than in the currency options suggests currency futures are more a speculator's market, whereas the option market may be more a hedger's market.

每天貨幣期货的流通量相对于未平仓合约(在季底依然開放的未來合約數量)，比货币期权要高。。。這表明货币期货，相較之下，是一個投机者的市場，而货币期权則是避險的市場。（短线交易者比较多，所以投机成分大）责任编辑：admin
