1.
At last,it is proved that when the control domain U is a bounded,closed set,the reachable set is the same as that when the control domain is the convex of U.
证明了具有约束控制半线性热方程系统的不能控性;满足一定条件的目标的可达性;最后证明了当控制区域U是有界闭集时,系统的等时区域与控制区域是U的凸包时的等时区域相同,推广了有限维的结论。
2.
It is proved in this paper that, the reachable set of system, in which the state varible is linear and control varible is nonlinear, must be boundedly convex-closed set provided that the control domain is boundedly closed set.
严格证明了，当控制区域为有界闭集时，状态变量为线性而控制变量为非线性的系统的等时区域是有界凸闭集，从而用等时区域方法能彻底解决这类系统的时间最优控制问题。
