nonlinear optimal control meaning in Chinese
非线性最优控制
Examples
- Modeling traffic flow evolution on urban expressway and nonlinear optimal control
城市快速路交通流建模及非线性最优控制 - The landing of a helicopter in autorotation is formulated as a nonlinear optimal control problem
本文将直升机的自转着陆过程定义为一个非线性的最优控制问题。 - This paper studies optimal helicopter flight operations in the event one - engine failure . a three - dimensional point mass with a yawing motion of uh - 60a has been used to study rto and cto from an elevated heliport or from a heliport , a first order dynamic of the oei contingency power is considered . flight after engine failure are formulated as nonlinear optimal control problems
双发及多发直升机单发失效后,直升机飞行所需要的功率由剩余发动机提供,而在某些需要大功率的飞行状态时,如起飞状态、着陆状态等,剩余发动机提供的功率可能满足不了,这就需要对剩余发动机的可用功率进行合理利用。 - Abstract : in this paper , the nonlinear optimal control problem connected with the ordinary differential system is considered , two modifications to the standard gradient procedures are constructed . the presented methods are based on the qualitative approximations of the cost functional . for linear - quadratic problems , the modifications have the property of the nonlocal improvement in contrast to the standard gradient procedures . some results relating to the convergence of the new methods are proved
文摘:讨论非线性最优控制问题构造的标准梯度方法的两种改进方法.文中的方法是以罚函数的有效近似为基础，与标准梯度方法相比，该方法对于非线性二次问题具有非局部的特点，同时给出相关收敛结果 - The cost function of the optimal control problem is a weighted sum of the squared horizontal and vertical components of the helicopter velocity at touchdown . the control ( horizontal and vertical components of the thrust coefficient ) required to minimize the cost function is obtained using nonlinear optimal control theory
其次，定义最优控制问题的性能指标为直升机着陆时的水平和垂直速度的加权平方和为最小，并采用一阶梯度算法得到使性能指标最小的控制规律。
