【摘要】 本文研究复杂气动系统的时序逻辑线路的设计理论与方法,这种复杂气动系统中不仅包含着干有两个行程阀的单往复或多往复气缸,还可包含若干有多个行程阀的多往复气缸。文中重新定义了对偶状态区间,用集合代数论证了消障制约信号的存在规律及其寻找方法。大大改进了文[1]提出的状态区间法。更多还原

【Abstract】 This paper again Studies the design theory and method forsequential logic circuit of the complex pneumatic system,whichconsists of not only some single-or multi-reciprocal actuatorswith two limit valves but also some multireciprocal actuators witha number of limit valves.The author redefines the dual stateinterval(DSI),proves the objective law about the existingrestricting signals to eliminate unwanted signals and the method todetermine restricted signals by general principles of algebra ofsets.Substantially he improves the state-interval method proposedin Ref.[1].更多还原
