摘要
作为一种新近提出的力学系统的离散优化控制模型,DMOC在大步长时易产生控制力的波动,对控制力的平稳输出非常不利。将平滑项引入DMOC模型,可以保证控制力的稳定。卫星变轨的数值仿真结果表明,平滑项的引入能够使控制力最小化的同时,保持控制力平稳变化。
Abstract
As a recently developed discrete optimal control model for mechanical system, discrete mechanics and optimal control (DMOC) suffers fluctuation of control forces when discrete step is large , which is unfavorable for stable output of control forces. With smoothing term added to DMOC model, stability of control forces can be acquired. Numerical simulation results of the satellite orbit transferring show that the introduction of smoothing term can keep control forces change smoothly while minimizing the total control forces.
