Output tracking problems for non minimum phase system existed in many practical problem, such as aircraft flight controlling, spacecraft launching and flexible manipulation, are considered.
The paper discusses both of the recursive and non - recursive solution of the Hanoi problem and delivers a non - recursive solution, which is better than the existed recursive one.
对“梵塔”问题的递归和非递归解进行了讨论;提出了较递归解法更好的非递归解法;

An analytical confirmation was presented for whether the non-over constrained 5-DOF parallel manipulators were existed, that is still an open diffcult problem in the mechanism field.
