Design and Implementation of PI Controller in a Two Tank Interacting Process using Lab View Software

In process industries, it is quite difficult to control the level of liquid in the tank.The processes having more than one controlled loop are called as multiple input multiple output or multivariable process, which are very often found in power plants, refinery processes, and chemical industries and in many industrial processes.The process with MIMO system (Two tank interacting process) is difficult to control the multiple variables so the level of fluid in the tanks and interaction between tanks need to be controlled. The problem of level control in interacting tank processes are system dynamics and interacting characteristics. The PI controller is equipped with the MIMO system to obtain good performance of the systemby using LABVIEW software.
