Abstract
In this paper, 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 paper, 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.
