摘要
本文导出一般性离散型Ｈ２优化控制问题存在唯一解之充分和必要条件．我们的结果显示，如果一离散型Ｈ２优化控制问题有解，那么其解是唯一的充分和必要条件为：①从控制输入到被控制输出之传递函数是左可逆，及②从干扰输入到测量输出之传递函数是右可逆．
A set of necessary and sufficient conditions under which a general discrete timeH2optimal control problem has a unique solution is derived. It is shown that the solution for a discrete time H2-optimal control problem,if it exists,is unique if and only if i)the transfer function from the control input to the controlled output is left invertible,and ii)the transfer function from the disturbance to the measurement output is right invertible.
