摘要
本文提出了一种以线性二次型调节器为基础的最优直流调速系统综合设计方法,分析了单输入系统开环和闭环特征多项式与加权矩阵之间的关系。首先,根据时域性能指标要求确定一个或一个主导极点,然后,利用前述的关系可以得到一个既具有良好动态响应,又满足工程约束条件的最优闭环系统。
A desing method of optimal DC speed control systems based on the linear quadratic regulator is presented in this paper.The relation between the open loop characteristic polynomial and closed-loop characteristic polynomial and weighting matrix Q is analysed for single input systems. In the first place a dominant pole is determined according to the time-bomain penformance; Seconbly, a optimal closed-lood system with good responses anb engineering constraints is gained byusing the previous relation.
