    Abstract: In this study, the design and analysis of
coupled tank water level control system is done using
robust control theory. The main aim of this work is to
improve level controlling mechanisms in industries and
household areas. In this study, H∞ and μ-synthesis
controllers are designed to improve the level control
system. The coupled tank water level control system is
designed using the proposed controller’s comparison and
tested for tracking a reference level signals (step, sine
wave and random) and simulation results have been
analyzed successfully. Finally, the comparative simulation
results prove the effectiveness of the proposed coupled
tank water level control system with H∞ controller for
improving the tracking mechanism performance of the
system.
