摘要
针对特征结构配置方法设计控制系统过程中系统参量难以测量的问题,设计了以容易测量的系统输出和控制输入作为输入的参数观测器。为提高特征结构配置方法设计系统的鲁棒性,充分发挥特征向量的作用,推导了系统特征向量与系统鲁棒性之间的关系,并在此基础上建立了多目标系统优化模型,给出了符合鲁棒性要求的特征向量计算方法,并通过算例验证了该方法的可行性和有效性。
In view of difficult measurement of system parameters given by eigenstructure process control system, parameter observer which takes system output and control input that can be easily measured as input was designed. In order to improve robustness of eigenstructure assignment method design system, maximize performance of feature vectors, the relation between system eigenvectors and robustness was deduced, based on this, a multi-objective optimization model was established, eigenvector calculation method which meets requirement for robustness was given, feasibility and effectiveness of the method were verified.
