on the control laws of linear delay systems 线性跟踪系统的控制律
the h model reduction problem of a kind of uncertain nonlinear systems with multiple time delays is studied . model reduction methods are presented that can simplify the uncertain nonlinear systems with multiple time delays to be low order linear delayed systems or low order linear systems, or even the zero order input-output mappings . the output tracking problem of disturbed nonlinear systems is solved by the h control theory, the analysis method is proposed 探讨了多时滞非线性系统的h_模型简化问题,将高阶的不确定多时滞非线性系统分别简化为低阶的线性时滞系统、低阶的线性系统甚至简单的零阶输入输出映射;应用h_控制理论解决了受扰非线性系统的输出跟踪问题,给出了分析此类问题的一般方法;总结并说明了h_滤波问题可解的充分条件。
