Liquor fermentation is a complex biochemical process, to control the temperature of fermentation tank fastly and accurately in the process can improve the efficiency and quality of fermentation .Because of the nonlinear and time lag of the process, meanwhile the conventional PID control and is difficult to solve practical problems in precise control,So this paper puts forward a fuzzy predictive controlling method, by combining the advantages of fuzzy control and predictive control for big lag, nonlinear fermentation systems.After using MATLAB to make comparative data simulation, the result shows that the proposed design method can better dynamic and static characteristics of both system, with static characteristic small overshoot, fast response, high steady precision, etc, can be useful in industrial control systems.

Three-channel PID controllers are widely used in industrial control systems. It is noted that the popularity of PID controllers in the control of industrial processes is explained by their ability to ensure high quality of processes in a wide range of modes, as well as functional simplicity that allows engineers to operate them without any problems.

Limited Scope

The virtualization technology has a great potential to improve the manageability and scalability of industrial control systems, as it can host and consolidate computing resources very efficiently. There accordingly have been efforts to utilize the virtualization technology for industrial control systems, but the research for virtualization of traditional industrial real-time networks, such as Controller Area Network (CAN), has been done in a very limited scope. Those traditional fieldbuses have distinguished characteristics from well-studied Ethernet-based networks; thus, it is necessary to study how to support their inherent functions transparently and how to guarantee Quality-of-Service (QoS) in virtualized environments. In this paper, we suggest a lightweight CAN virtualization technology for virtual controllers to tackle both functionality and QoS issues. We particularly target the virtual controllers that are containerized with an operating-system(OS)-based virtualization technology. In the functionality aspect, our virtualization technology provides virtual CAN interfaces and virtual CAN buses at the device driver level. In the QoS perspective, we provide a hierarchical real-time scheduler and a simulator, which enable the adjustment of phase offsets of virtual controllers and tasks. The experiment results show that our CAN virtualization has lower overheads than an existing approach up to 20%. Moreover, we show that the worst-case end-to-end delay could be reduced up to 78.7% by adjusting the phase offsets of virtual controllers and tasks.

Waste generated from industries and from various places around us not only contains rubber or plastics but contains lot many harmful pollutants whichare hazardous if disposed continuously in open and leftto degrade in our environment.Our project aims to study properties of different materials which may help in utilising the waste as well as improve the quality of roads and make them efficient, stable, durable and long lasting. Some of the materials that we have studied and considered to be tested in the partial replacement of bitumen are PMB and CRMB.
