When the maximal uncontrollable subnet is loop - in , the problem is a nonlinear integer program ( nip ) , which is difficult to be solved 当最大不可控子网中有环时,控制律的求解变成了非线性整数规划( nip )问题,而nip问题的求解是非常困难的。
In this paper , for the maximal uncontrollable loop - in subnet with a special form , the maximal permissive control policy is obtained through applying the lip to the loop - free subnet that is equivalent to the maximal uncontrollable loop - in subnet 本文针对一类最大不可控子网有环的petri网,通过把有环的最大不可控子网等价为无环不可控子网进而应用lip方法来得到最大容许控制律。
