Parametric analysis of Quadruple conical tank system

Modified Quadruple conical tank system is benchmark a laboratory setup for testing of various linear and nonlinear control algorithms for the multivariable control system. This novel arrangement of quadruple conical tank system provides multiple process configuration for multivariable input-output. This paper presents the hardware structure of quadruple conical tank, computer interfacing using LabVIEW software, mathematical modelling of system and dynamic behaviour study. Additionally, paper explores the open loop response based parametric analysis for different input and output configurations with various operating points of quadruple conical tank system using linearized model obtained from LabVIEW. Through comparative studies of open loop response in simulation environment and real-time hardware system, the effect of interaction, coupling, time variations and change in dynamic behaviour of QCTS confirmed.
