چکیده
In this paper, two new versions of modified active disturbance rejection control (MADRC) are proposed to stabilize a nonlinear quadruple tank system and the water levels lower tanks in presence exogenous disturbances, parameter uncertainties, parallel varying input set-points. The first scheme is configured from combination tracking differentiator (TD), super twisting sliding mode (STC-SM), extended state observer (NLESO), while second obtained by aggregating another TD, error feedback (MNLSEF), fal-function-based ESO. MADRC schemes with investigated running simulations MATLAB/SIMULINK environment several comparison experiments conducted validate effectiveness schemes. Furthermore, genetic algorithm (GA) used as tuning parametrize integral time absolute (ITAE), square signal (ISU), (IAU) an output performance index (OPI). Finally, simulation results show robustness noticeable reduction OPI.

Linear and Nonlinear Model Predictive Control of Quadruple Tank Process
In a multi input and output (MIMO) process mathematical modeling of the physical systems has gained importance due to the complexity of interactions within the system. All the parameters used in a model cannot be determined accurately. The major problem in a multivariable process is that loop interaction can arise and cause difficulty in feedback control design. This problem can be solved using...
متن کاملModel Predictive Control for the Modified Quadruple Tank System
In this paper, we present in a tutorial fashion the implementation of Model Predictive Control (MPC) on a virtual model of the modified quadruple tank system. The modified quadruple tank system is an example of a multi-input-multi-output (MIMO) system with known and unknown disturbances. Model Predictive Control is well known for its ability to deal with multivariable and complex control proble...

In this paper, a predictive control based on the proposed hybrid model is designed to control the fluid height in a three-tank system with nonlinear dynamics whose operating mode depends on the instantaneous amount of system states. The use of nonlinear hybrid model in predictive control leads to a problem of mixed integer nonlinear programming (MINLP) which is very complex and time consuming t...
متن کاملRobust Control of a Two Tank System Using Algebraic Approach
The paper deals with design of a robust controller via algebraic μ-synthesis for a two tank system, which is a well known benchmark problem. The controller is obtained by decoupling two-input two-output system into two identical SISO (Single-Input Single-Output) plants. The task of robust controller design is then performed by finding a suitable pole placement for the SISO systems. The robustne...
