摘要:
针对传统用户自定义指标在评估离散系统性能时没有考虑内部结构的不足,提出了基于改进用户自定义指标的评估方法。该方法将传统用户自定义基准中的开环时滞和干扰分别替换为部分闭环回路中的有效时滞和干扰,使用丢番图分解用户自定义函数的最小方差响应,进而求得性能指标。同时采用右对角线关联矩阵取代单位关联矩阵,简化了求解性能指标的复杂度。仿真结果证明,该方法计算量小,对有无内部干扰的离散系统均可准确评估。
Abstract:
In view of that the internal structure of the decentralized control system is ignored when its performance is evaluated by the traditional user-specified benchmark,the improved user-defined benchmark is proposed here.The open-loop delay and the disturbance of the traditional user-specified benchmark are respectively replaceed by the effective partially closed-loop delay and disturbance.Diophantus is applied to analyze the minimum variance response of the user-specified function to get the performance indicator.The right diagonal interactor matrix replaces the unit interactor matrix to simplify complexity of solving performance indicators.The simulation results prove that this method can evaluate the decentralized control system whether the system has the internal disturbance.
