摘要 针对有限时间线性二次型终端控制问题,提出了新型终端控制算法.该算法采用了扫掠法和转移矩阵法两种求解方法.以OH-6A型直升机自主软着陆控制为例,对新终端控制算法和硬终端控制方法进行了数值实验和比较,实验证明了新终端控制算法有效可行,比现有的硬终端控制算法缩短了计算时间和减少了反馈增益. A novel terminal control algorithm for the finite-horizon linear quadratic(LQ) terminal control problem is proposed.The algorithm adopts two solving methods:sweep method and transit matrix method.It is applied to the automatic soft landing control of OH-6A helicopter.Numerical experiments and comparisons between the novel terminal control method and hard terminal control method show that the new algorithm is feasible,and has less feedback gains while consumes less computation time than existing hard terminal control.
