摘要

研究了一个综合最优控制问题。为了解决这一问题,首先要解决控制对象相对于状态空间中某一点的稳定控制系统综合问题,然后再解决最优控制的第二个问题,即寻找从初始位置到终端位置的一些质量准则值最优的稳定点。对于第一个问题,使用了网络算子方法。利用进化算法以有向计算图的形式求得反馈控制系统的数学表达式。对于第二个问题,采用粒子群算法求解。在实验中,控制对象是一对机器人,他们将一辆由刚性铰链连接的小车从起点移动到终点,试图避开障碍物。

A Solution of Synthesized Optimal Control Problem for Interaction of Robots by Evolutionary Computations
A paper considers a synthesized optimal control problem. To solve this problem, it is necessary to solve the problem of control system synthesis for stabilization of control object relatively a point in the state space, and then to solve the second problem of optimal control to find some stabilization points for movement from initial position to terminal one with the best value of the quality criterion. For the first problem a network operator method was used. It finds a mathematical expression of a feedback control system in the form of oriented calculating graph by evolutionary algorithm. For solution of the second problem a particle swarm optimization was applied. In experiment the control object is a pair of robots that move a cart joined by rigid hinged hitch from initial point to terminal one trying to avoid obstacles.
