A novel input/output feedback linearization control method by utilizing nonlinear disturbance
observer (NDOB) is proposed for a quadruple-tank liquid level (QTLL) system in this paper …

Often in a coupled two tank MIMO system, the level of the first tank is required to be kept at a
constant level while the level of the second tank is required to follow a time varying …

The paper deals with the level control of two coupled tanks. A static sliding mode control
scheme is proposed for the system. To greatly reduce the chattering problem associated …

In this paper, considering the disturbance in the four-tank system, the new active disturbance
rejection control strategies are proposed to resolve the disturbance problem. In the first …

The process investigated herein is the quadruple tank system that is stable only within a
limited zone of operating parameters. The process model has been developed from …

The control of tank systems in industrial applications is an important issue for monitoring the
chemical processes involved in the manufacture and delivery of product. The most important …

This paper presents the mathematical modeling of coupled-tank system and designing of
sliding mode control (SMC) for liquid level control in the system. The non-linear single-input …

This paper deals with the problem of model reference control for linear parameter varying
(LPV) systems. The LPV systems under consideration depend on a set of parameters that …

(57) ABSTRACT A mixing system is provided comprising a first mixing tub, a first actuator to
control flow of a carrier fluid, a sensor to determine a rate of flow of the fluid, and a second …
