针对基于Petri网离散事件系统库所和变迁混合不等式约束反馈控制器的设计问题,提出一项新型设计具有库所和变迁混合约束的Petri网控制器的方法———利用Petri网简化技术把所有约束库所融合为一个与它们标识总量相等的库所,然后再与受约束的变迁进行对照比较,使控制器的设计更为简单并且避免了死锁,尤其是对规模较大的系统,其优势更加明显。借助一个应用实例,将该控制器设计方法与Yamalidou等人提出的控制器设计方法作比较,表明所提出的控制器设计方法不仅更简单、更有效而且可以应用到推广Petri网。
Aiming at the design problem of Petri net discrete event system base and variable mixed inequality constrained feedback controller, a new method for designing Petri net controller with mixed constraints of place and transition is proposed. By using Petri net simplification technique, The confinement libraries are merged into one place equal to their total number of identities and then compared with the constrained changes to make the design of the controller easier and to avoid deadlocks, especially for larger systems, Its advantage is even more obvious. By means of an application example, the controller design method is compared with the controller design method proposed by Yamalidou et al., Which shows that the proposed controller design method is not only simpler and more efficient, but also can be applied to the extended Petri net.
