Implementation of the Quadruple Tank Process Using Computer Vision (original) (raw)

An Educational Plant Based on the Quadruple-Tank Process

IFAC Proceedings Volumes, 2006

This paper presents an experimental tank system developed at the University of Seville for process control education. This plant is based on the well known quadrupletank process and some modifications have been done in order to obtain a wide range of applications. The quadruple tank process is a multivariable laboratory plant of interconnected tanks that can be easily configured to exhibit the effect of multivariable zero (minimum and non-minimum phase) on the system behavior, as well as the effect of non linear dynamics, saturation, constraints, etc. In the real plant implementation, the original structure of the process has been modified to offer a wide variety of uses for both educational and research purposes.Thus, different plants can be configured such as one single tank, two or three cascaded tanks, a mixture process and hybrid dynamics. Moreover the dynamics parameters of each tank can be set up by tuning the cross-section of the outlet hole of the tank. Furthermore, the real plant has been implemented using industrial instrumentation and a PLC for the low level control. Supervision and control of the plant is carried out in a computer by means of OPC (Ole for Process Control) which allows one to connect the plant with a wide range of control programs such as LabView, Matlab or industrial SCADA.

Process Dynamic and Control Modified II Quadruple Tank on Labview Application

2016

In general, industrial processes have a multi-variable characteristic, which is sensitive to the disturbances. Therefore, it is important to study the influences of disturbance through a simple but reliable tools. Quadruple tank is a simple tool in process control that represents a complex multivariable dynamic process. This article investigates the effects of an introduction of heaters to the system as well as the interaction among the tanks. The flow rates and energy inputs to the tanks, respectively, are considered as the manipulated variables, while the liquid temperatures and level are controlled; hence the system becomes a 4x4-MIMO. The closed loop simulation is designed for comparing controlled variable response between P only-PID and IMC conroller. Error criteria is evaluated by IAE. In level change of minimum phase, IAE’s value of level and temperature controller IMC show better result than P-only. On the contrary, P-only controller indicated faster response (settling time)...

Digital control of a tank system

IEEE Transactions on Education, 1994

This paper describes the laboratory environment for experiments in digital control of a coupled tank system. The control process consists of upper and lower containers with draining orifices. As the cross section of the lower container varies with the level, the dynamic of the process changes extensively with the selected steady-state operating level. Measurements of the tank levels are available, while the flow rate into the upper tank is forced by a pump driven by an electric motor. A nonlinear model is employed to study various features of the process. The control strategy is to stabilize the level in the lower tank by adjustment of the flow rate into the upper tank. An IBM AT, equipped with an universal analog input/output board is used to control the process. The interactive real-time software frame, available under MS-DOS, uses selectable operating modes to analyze the performance of different control algorithms. Digital state-feedback algorithm is presented as an illustration.

Advanced Control for Quadruple Tank Process

JITEKI : Jurnal Ilmiah Teknik Elektro Komputer dan Informatika, 2024

Water is delivered from the reservoir to both the upper and the lower tanks. Pump 1 transfers water to tanks 1 and 4, while pump 2 supplies water to tanks 2 and 3. The manipulated variables of the QTP are the voltages applied to the pumps, denoted as and [V]. The controlled variables are the water levels of the two lower tanks, denoted as and [ ]. The split ratio is determined by the valve positions. Let's assume that the states of the system are the water levels of tank 1 to tank 4, denoted as

Control Schemes for a Quadruple Tank Process

2006

This paper deals with the control of a quadruple tank process. A gain scheduling controller, a linear parameter varying controller and an input-output feedback linearization controller are proposed for the quadruple tank process. The derivation of the three control schemes is presented in details. Moreover, the proposed control schemes are implemented using an experimental setup. The experimental results indicate that the developed control schemes work well and are able to regulate the output of the process to its desired value. Additionally, the implementation results demonstrate that the input-output feedback linearization controller gave the best performance.

Model and Control for Coupled Tanks using Labview

International Conference on Mechatronics, Electronics and Automotive Engineering, 2013

This paper presents a digital proportional-integral controller implementation for a Coupled Tanks System for liquid level control. The model identification is done by sinusoidal signal at different frequencies, as result the bode plot obtained is applied for designing the controller. One of the main advantages of programming the digital controller in Labview is the possibility of sending small gains which allow to get a better performance for fixing the parameters: settling time and overshoot. Since the system is nonlinear the mathematical model is also presented to compare with the experimental model obtained. The obtained results on simulation are shown as well as the implementation of two PI controllers one in the control module that has the tanks system used (CE105MV) and another in Labview.
