| 针对基于Petri网离散事件系统库所标识不等式约束反馈控制器的设计问题,提出一项新型网简化技术--标识总量保持网简化技术,并利用此项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,使控制器的设计更为简单,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Moody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更简单、更有效. |

| Abstract: |
| The problem of constructing a Petri net feedback controller, which enforces the conjunction of a set of linear inequalities on the reachable marking of the plant modeled by Petri net, is discussed in this paper. A new net reduction──HMSNR (holding marking sum net reduction), is presented, which fuses all the constrained places into one place whose marking is equal to the sum of the markings of the constrained places. The net reduction eases design of controller and holds remarkable advantage especially for the systems with large scale. The method is proved to be simpler and more efficient than the method presented by Moody, et al., using an applied instance that is also used by Moody, et al. |
