Full Order Observer Controller Design for Two Interacting Tank System Based on State Space Approach

ABSTRACT The control of liquid level in tank system and flow between tanks is main problems in process industries. Thus, the control of liquid level in tank system and flow between tanks which is must be controlled. The control of level of tank in the interacting system is major task. The main objective of this paper is to determine the mathematical model of a coupled tank system which will be useful for designing and to implement full-order observer using the software packages for computer aided control system design in MATLAB. A state feedback gain matrix is designed for the interacting tank systems with the help of poleplacement technique. Observer estimation errors are presented by choosing the observer(s) initial conditions. The proposed study of this observers and observer based controllers may find application in numerous engineering and scientific industrial problems.
