(Supervisor)2022-06-152022-06-152019https://dspace.univ-boumerdes.dz/handle/123456789/945542 p.In control engineering, a single-input and single-output (SISO) system is considered as a simple system. However, numerous systems are not such uncomplicated, they have various data sources and returns. These systems are called multi-input and multi-output (MIMO) systems. Basic MIMO frameworks have some challenges since they are enormous and complex. Moreover, they have nonlinearities and loop interactions between their inputs and outputs. On the motivation behind considering multivariable systems, the quadruple tank process (QTP) is selected as a benchmark. This process is suitable for examining linear and nonlinear controllers and exhibits minimum and non-minimum system behaviour by essentially changing the setup of valve position. The PID and fuzzy Logic controllers of the nonlinear process (QTP) model is simulated in MATLAB/Simulink. The obtained results from simulation of the two controllers as well as system dynamic performances are discussed.enFuzzy logic controlSISO system : MIMO systemQuadruple tank process (QTP)Thesis
