PID controller tuning for Honeywell and Emerson is done by controller gain (Kc) and for Yokogawa & Foxboro is done by proportional band. Ziegler-Nichols, Cohen-coon, Lambda tuning etc. PID controller tuning is done by various methods i.e. Engineer trained for a particular Process Instrumentation application using PID from say Honeywell can not immediately adopt the operation of say Yokogawa PID.
Language of PID controller and programming differs from manufacturer to manufacturer. The operation of PID controller used in process is as per programming done. PID controllers are manufactured by Honeywell Experion, Emerson – Delta V, Foxboro, Yokogawa, GEFRAN etc. The job of a typical control system is to maintain something that is variable or changeable in a prescribed state. PID controllers are used in control systems which are being used in the automated processes in industries. The PID controller means Proportional Integral Derivative Controller used in many industries to compensate the tracking errors occurred in the various processes. To control these parameters PID controllers are used.
I.Ī typical Process Instrumentation, four parameters are important – flow, temperature, pressure and level. KEYWORDS: PID, LabVIEW, simulation, control, industry, real time.
NI PC add on DAQ card is used for interfacing with the hardware. This designing is possible using LabVIEW – proprietary development by National Instruments (NI). The aim of our paper is to replace the traditional PID instrument with virtual, soft PID that has same controlling capabilities as that of traditional instrument. It becomes necessary to improve traditional instruments. As the time going, the traditional instruments are appearing the shortages. The measurement and control technology plays an important role in the process of production.
