摘要
对由一系列传输带构成的运输系统的混合系统控制问题进行了研究,建立了基于自动机原理的传输带混合控制模型.将混合控制系统中离散事件的变换过程用真值表表示,并设计出相应的逻辑电路图以实现自动机的功能,从而实现控制综合的目的.结果表明,对此类混合系统的控制综合可以利用基于离散事件系统监督控制的方法来实现.
The control problem of a hybrid system (HS) for a transportation system consisting of a line of conveyor belts is investigated. A model of the hybrid control system (HCS) for the transportation system based on automaton principle is also established. It can achieve good control synthesis for the HCS if the transformation process of the discrete event in the HCS is expressed with truth table, and the corresponding logic circuit is designed to realize the function of the automaton. It is shown that the control synthesis based on supervisory control of discrete event systems can achieve good performance for the class of HS.
