Designing of Intelligent Expert Control System Using Petri Net For Grinding Mill Operation
The paper utilizes Petri_like_net structure in developing an intelligent expert control system to achieve optimum grinding by regulating the parameters of the grinding mill. The work establishes an appropriate theoretical background that helps to predict dynamic breakage characteristics of particle size distribution of materials, adequately supported by experimental data. Feed forward neural ne...
متن کاملPetri Net Modeling of Transformer Fault Diagnosis Process
Transformer fault diagnosis and repair is a complex task that includes many possible types of faults and demands special trained personnel. In this paper, Petri Nets are used for the simulation of transformer fault diagnosis process and the definition of the actions followed to repair the transformer. An oil thermometer and a Buchholz relay are used for transformer fault detection. Simulation r...
متن کاملFault Diagnosis of P-Time Labeled Petri net Systems
This paper focuses on the fault diagnosis problem of systems modeled with P-time labeled Petri nets with partial information. Indeed, the set of transitions is partitioned into those labeled with the empty string ǫ called silent (as their firin cannot be detected) including the faulty transitions and the observable ones. The proposed approach is based on the synthesis of a function called diagn...
متن کاملSubstation Fault Diagnosis Based on Time Sequence Fuzzy Petri Net
As the 750kV substation has the characteristics like timing inconsistency, dual protection configuration and uncertain diagnosis result, a fault diagnosis method of substation with redundant protection configuration based on time sequence fuzzy Petri nets is proposed. In this method, redundant knowledge about fault component is represented by using two sets of protective information. On that ba...
متن کاملColored timed Petri net based statistical process control and fault diagnosis to flexible manufacturing systems
The quality consistence and machines’ utilization of a flexible manufacturing system (FMS) strongly depend on the statistical process control (SPC) and the correct fault diagnosis of equipments. An FMS can be modeled by the Colored Timed Petri Net (CTPN). However, the CTPN models of most FMSs lack the activities of the statistical process control (SPC) and fault diagnosis, and they lead to the ...
