This approach is based on object-oriented and agent-based methods, and aims at overcoming the difficulties associated with managing real-time reconfiguration of an intelligent manufacturing system. As a conventional PID controller has deficiencies in adapting to the environmental changes, a supervisory fuzzy controller based on Artificial Intelligent (AI) is required to adjust the PID controller inputs., hence an AFPID controller is designed here to adjust the three PID parameters (kp,ki,kd) online in SDCS. The first one is the distribution of various control functions into relatively small sets of subsystems, which are of semiautonomous, and are interconnected through a high speed communication bus. In the study presented in this article, an The controllers are networked to a central console.
