双线性系统最优控制的一种迭代方法

An Iterative Procedure for Optimal Control of Bilinear Systems

Hamidreza Ramezanpour, Saeed Setayeshi, Hossein Arabalibeik, Amin Jajarmi

摘要:

本文提出一种求解双线性二次型最优控制问题的新方法。该方法首先利用庞特里亚金最大值原理将原最优控制问题转化为非线性两点边值问题(TPBVP)。然后,利用同伦扰动法(HPM)和在拓扑空间中引入凸同伦,将非线性TPBVP转化为线性时不变TPBVP序列。通过迭代过程求解后一问题,得到无穷级数形式的最优控制律和最优轨迹。最后,通过定理证明了这类级数收敛的充分条件。通过一个示例说明了该方法的简单性和有效性。

英文摘要:

This paper presents a new and straightforward procedure for solving bilinear quadratic optimal control problem. In this method, first the original optimal control problem is transformed into a nonlinear twopoint boundary value problem (TPBVP) via the Pontryagin's maximum principle. Then, the nonlinear TPBVP is transformed into a sequence of linear time-invariant TPBVPs using the homotopy perturbation method (HPM) and introducing a convex homotopy in topologic space. Solving the latter problems through an iterative process yields the optimal control law and optimal trajectory in the form of infinite series. Finally, sufficient condition for convergence of these series is proved by a theorem. Simplicity and efficiency of the proposed method is shown through an illustrative example.
