An implementation on matlab software for non-linear controller design based on linear algebra for quadruple tank process

Abstract:

This paper is focused on the design of a control algorithm based on linear algebra for multivariable systems and its application to control of a quadruple tank system. In order to design the controller, the system model is approximated by numerical methods and then a system of linear equations are solved by least square to obtain the optimal control actions. The strategy presented in this paper has the advantage of using discrete equations and therefore a direct implementation in most computer-driven systems is feasible. The simulation results developed on Matlab software shows the effective of the proposed method.
