【Abstract】 In this paper we address the problem of deadlock control in the automated guided vehicle system in automated manufacturing systems with uni directinal guided paths. A petri net model is developed for the problem. By using the PN model developed, the condition for deadlock free operation in AGV system and a control law are presented. To avoid deadlocks in AGV systems by this law, one needs only to observe the state of the system and check the number of free spaces available in some of the circuits. Thus, it is simple and effective, and can be used in the real time control.更多还原
