Distributed Control System provides advanced management ways to regulate the method parameters. In most industries, flow management encompasses a big selection of application. The flow control in pipeline is shown and also the process of bottle filling using distributed control system is mentioned. Some of the advantages are, it helps to reduce the time required by the process to complete, as it can be automatically handled, it can reduce the labour cost, it also gives the ease to control and monitor real time condition. Distributed Control System has plethora of advantages as compared to any other control system. Distributed Control System is nothing but a computer controlled software application which is designed to work on the computer to complete the desired process by providing it with all necessary devices. Amongst all the control systems, Distributed Control System is widely being used and is more popular in modern industrial processes. Therefore, PID tuning is essentially an engineering art that cannot only rely on automated processes but requires the experience of the designer.In following paper the aim is to mention all the possible methods that can be used to control the flow and the applications of DCS in industrial sector. A variety of techniques such as Gain scheduling are employed to deal with this fact. As the PID is controller, it naturally cannot maintain an equally good behavior for the full flight envelope of the system. With the exception of hover/or trimmed-flight, an aerial vehicle is a nonlinear system.The integral term needs special caution due to the often critically stable or unstable characteristics expressed by unmanned aicraft.The control margins of the aerial vehicle have limits and therefore the PID controller has to be designed account for these constraints. LabVIEW Control Design and Simulation Module, LabVIEW PID and Fuzzy Logic.
Among others, the following important issues have to be considered when designing flight control functionalities using PID controllers: Real-life implementation of PID controllers is however a much more elaborated process. Nowadays, modern tools exist to optimally tune such control laws. The PID controller is so successful both due its powerful performance and its simplicity. A fractional order PID controller was designed for liquid level in spherical tank using MATLAB which compared the performance of fractional order PID with.
