Modular Production System Control Using Supervisory Control Theory Method

Abstract

Modular Production System (MPS) is a mini industrial automation process that simulates product processing. MPS uses a Programmable Logic Controller (PLC) to observe and control system processes. The MPS used is the Festo Processing Station which is composed of several components that are numerous and varied so that the control is quite difficult, especially when using a basic PLC program. Therefore, this paper proposes that MPS is classified as a Discrete Event System (DES). The method used to control DES is the Supervisory Control Theory (SCT). MPS is used to process two types of materials (metal and non-metal). The drilling process is carried out only for metal. PLC-based MPS is successfully controlled using the SCT method. MPS with the SCT method can process the material with 100% success. The PLC program using the SCT method can save data memory by 2.3% compared to without SCT.
