中文摘要：
研究了一类事件驱动的变结构动态系统的非光滑最优性条件．通过引入一个新的时间变量，将变结构动态系统的最优性问题转化为古典动态系统的最优性问题．基于广义微分和古典动态系统的最优性理论，得到了该系统的Frechet上微分形式的必要性条件，推广了已有文献的相关结论．结果表明，在系统的连续运行过程中，控制变量、协态变量和状态变量满足最小值原理和协态方程．在系统的运行模型发生改变时，协态变量产生一定的跳跃，哈密尔顿函数连续．最后通过一个算例说明了该结论的有效性．
英文摘要：
In this paper, non-smooth optimality conditions for a class of event-driven dynamic systems with variable structure are investigated. By introducing a new time variable, the dynamical optimal problems with variable structure are transformed into classical optimal problems. Based on the knowledge of generalized differential and clas- sical optimal theory, necessary optimality conditions of Frechet superdifferential form for this dynamic system are obtained, which generalize some existing relevant results. It is shown that, in the continuous process of the system, the control variable, the adjoint vari- able and the state variable satisfy the adjoint equations and the minimum principles. At the changing instants of the system model, the adjoint variables make certain jump and the Hamiltonian is continuous. At last, one example is given to illustrate the efficiency of the main results.
