A NEW DIRECT DECOMPOSITION METHOD OF TWO-LEVEL HIERARCHICAL CONTROL FOR THE LARGE SCALE SYSTEM
-
摘要: 提出一个新的递阶控制的分解协调方法，它是由最优化问题的直接梯度解及性能函数的一个柔性分解组成。通过性能函数分解的自由度得到所需要的混合结构控制律，其下层控制器是闭环控制部分，上层是保证全局系统最优化的开环控制部分。局部性能函数的柔性选取，使两层优化任务的重新划分既能离线计算，也能在线修正．Abstract: In this paper, a new decomposition-coordination method of hierarchical control is presented, it consists of a direct gradient solution of the optimization problem, together with a free flexibility decomposition of the cost-function. Using the freedom of the cost-function decomposition the desired mixed structure control laws are obtained. The low-level controller is a closed-loop term, while at the higher level an open-loop term guarantees the optimality of the global solution. Moreover, the method offers a great flexibility in the choice of the local cost function indices, this the repartition of the task between the two levels can be either off-line computation or on line regulation.
