摘要
提出了一种以线性二次型性能指标为基础的综合性最优控制问题,研究了单输入系统开环和闭环特征多项式与性能指标中的加权矩阵之间的关系,根据这些关系可以确定一个具有指定闭环极点的最优控制系统,最后把它们应用于双闭环直流调速系统中的速度调节器的设计。仿真结果表明,这种设计方法是可行的,且具有比较令人满意的设计效果。
This paper puts forward the problem of comprehensive optimum contro l based on linear quadratic performance index, studies on the relations between th e open loop / closed loop characteristic polynomial of single input system and t he weighted matrix in performance indexes, according to which an optimum control system with pointed closed loop's vertexes can be determined, and these can be applied into the design of the governor in double closed loop D.C. governing sys tem. The simulation results show that this design method is feasible and can get more satisfactory effects.
