摘要:
分析了时变目标函数及其最优解的时变性能,提出了跟踪时变目标函数最优解的一阶和二阶方法,其中二阶方法能使时变目标函数最优解的跟踪以指数速率收敛. 应用时变最优化方法,可以直接在线辨识连续线性系统、时滞系统和非线性系统,并能随时跟踪和检测系统时滞和参数的变化从而获取系统的最新信息.
Abstract:
The variation of a time-dependent objective solution is analyzed. A first-order technique and a second-order technique for tracking the optimum are proposed. The second-order technique ensures the tracking to converge exponentially. Applying time-dependent optimization, the continuous linear system without time-delay, the time-lag linear system and nonlinear system can be on-line identified directly. This method can track and detect the variation of the parameters and time-delay immediately, and thus can obtain the latest information of the system.
