Fuzzy control implementation in low cost CPPS devices

Abstract

In the present day, industry has been brought closer to the Industry 4.0 paradigm due to its needs of reaching better industrial communications and improving the control process. According to the IIoT concepts, Cyber Physical Production Systems (CPPS) are normally connected to each other, and also connected to the virtual world of global digital networks. By introducing the IEC-61499 standard, CPPS will be allowed to implement flexible, reconfigurable, and distributed controllers. Fuzzy controllers are an advanced control solution that adds certain level of human reasoning to the system, making it possible to obtain a suitable alternative for traditional controllers. Due to the requirement of IEC-61499 of using as controller device an embedded platform, the encapsulation of advanced techniques of control in the algorithms of a systems becomes more simple and efficient. This is why it is necessary to provide the industry with low-cost alternatives who can easily integrate more complex and efficient controllers, making it possible to redirect the CPPS development to a new variety of devices. This paper proposes the development of the Function Blocks (FBs) needed in order to create a distributed control system based on Fuzzy Logic to control an analog process.
