MODELLING AND CONTROL OF MULTI PROCESS SYSTEM USING BOND GRAPH AND DECENTRALIZED MODEL PREDICTIVE CONTROLTECHNIQUE

📄 Project Abstract

This research proposes a simplified approach to the modelling of quadruple tank system via the use of bond graph technique. The novelty of this approach is that quadruple tank system equations are easier to obtain. In addition, the process of obtaining the system equations is less prone to error because of the use of the pictorial advantage of bond graph. This is an advantage for complex systems such as Multi Input Multi Output (MIMO) systems. The 20-SIM software (bond graph technique software) was used in this work. In order to address the inherent multivariable constraint issues of the quadruple tank system such as looping and coupling effects, while minimizing the cost of control, the quadruple tank system was partitioned into Single Input Single Output (SISO) systems. This established the basis for the implementation of the Decentralized Model Predictive Control (DMPC) for the quadruple tank system. Due to the numerical ill-conditioning of the system state equations, a Quadratic Pr...
