摘要
讨论了一类跟踪最优控制问题的次优解法。采用亏数为2的分段三次样条描述方案使泛函极小问题转化为多变量参数寻优问题。使用Newton-Raphson迭代方法并讨论了减少计算量的技术以及状态初值的修正方法。给出了一个来自实际的应用例,表明这种次优解法具有工程实用价值。
A sub-optimal solution of a class of optimal tracking control probem is proposed, which converts the functional minimization problem into multivariable parametric minimization problem by using a parameterization description of control function through cubic splines with deficiency number 2. Newton-Raphson iteration scheme is applied and the technique of reducing computation cost is discussed. Also, the correction of inaccurate initial states is introduced. A practical application example is given and the effectiveness of the method of present article is clearly shown.
