摘要
考虑了二阶线性系统的比例微分(PD)反馈特征结构配置问题以及其在最优控制问题中的应用。基于比例微分特征结构配置参数化方法,将二阶线性系统的最优控制问题转化为一个便于求解的有约束条件的极小值问题,并给出了相应的求解算法。三自由度质量弹簧阻尼系统算例及其仿真结果表明所提算法简单、有效。
The problem of proportional plus derivative (PD) feedback eigenstructure configuration and its applications in optimal control problems are investigated in a second-order linear systems. Based on the parametric method of eigenstructure assignment via PD feedback, the optimal control problem in second-order linear systems is formulated as a constrained minimization problem and a corresponding algorithm for this minimization problem is proposed. A lumped mass-spring dashpot system with three degrees and the s...
